s, supports internal and external content storage, and connects to an online store called the Nintendo DSi Shop. This new functionality was intended to facilitate personalization, so as to encourage each member of a household to purchase an individual DSi.

Reviewers were generally positive in their reception of the Nintendo DSi; although they decried the console's lack of exclusive software and removal of the GBA cartridge slot, its added functionality caused many to recommend it to those who did not purchase previous DS models. Many critics were disappointed with the DSi's camera's limited resolution, but thought they were adequate for the handheld's screens. CNET

Kuwahara reported that his team had difficulty determining the potential market for the handheld during the design process; he said of their goal, "We have to be able to sell the console on its own. It also has to be able to meld into the already-existing DS market." The console's digital camera

. However, in order to improve portability without sacrificing durability, the GBA cartridge slot present on earlier models was removed. To compensate, Nintendo continued to support the DS Lite as long as there was consumer demand for it.
The DSi's original design included two DS game card slots, due to demand from both fan communities and Nintendo employees, which consequently made the design considerably larger. Kuwahara said of the console's in-company unveiling in October 2007 that "the response wasn’t that great, and, ... we’d sort of been expecting that." The second game card slot was removed, which made the handheld approximately 0.12 inches (3 mm) slimmer. Yui Ehara, designer of the DS Lite and DSi's casing, advocated to change the six speaker apertures, as their circular perforations were redundant to the rest of the handheld's interface. He believed that this alteration also signaled a clearer distinction between the DSi and its predecessors while keeping the unit "neat" and "simple". Ehara hoped the DSi's added features would not interfere with his desired iconic image of the Nintendo DS product line: two rectangles, one on top of the other, with each half containing another rectangle inside. This model was publicly revealed at the October 2008 Nintendo Conference in Tokyo, along with its Japanese price and release date. While the DS product line's worldwide yearly sales figures had consistently surpassed those of its primary market rival, Sony's PlayStation Portable, demand for it in Japan was decreasing; Nintendo's launch of the DSi was meant to stimulate sales. The company was less concerned with releasing the DSi in other territories, where market demand for the DS Lite remained high.

Development of a large DS Lite model in 2007 eventually became the DSi XL (known in Japan as the ). Nintendo had designed a large DS Lite model with 3.8 inches (96.5 mm) screens, compared to the standard 3 inches (76.2 mm) screens; development of this new handheld advanced far enough that it could have begun mass production

. However, consumer demand for the DS Lite and Wii stalled its release. Iwata pitched the idea of simultaneously releasing large and small versions of the DSi, but Nintendo's hardware team was incapable of developing two models concurrently. After finishing work on the DSi, Kuwahara jump-started the DSi XL project and became project leader. Various names for the DSi XL were considered, including "DSi Comfort", "DSi Executive", "DSi Premium", "DSi Living", and "DSi Deka" (Japanese for "large"). Mario

 over its predecessor, which allows onlookers to see the screen's contents more easily. This feature was absent from the large DS Lite model due to cost issues, which also limited LCD screen size to approximately 3.8 inches (96.5 mm). The cost of LCD screens is determined by how many pieces are cut from a single large glass sheet. Cutting these sheets so each DSi XL screen was 4.2 inches (106.7 mm) produced the least amount of wasted material.

On November 1, 2008, the DSi was released in Japan, in black and white; its April 2, 2009 release in Australia and New Zealand, and its April 3 release in Europe, featured these same colors. It launched in the United States and Canada on April 5, alongside the game Rhythm Heaven

, showed potential in further expanding the Nintendo DS gaming population—particularly in Europe and the United States. To further promote the product line while expanding its gaming population, Nintendo modified its market expansion approach. Iwata has said that families often share DS and DS Lite consoles, so to encourage each family member to buy an individual handheld, Nintendo added personalization features to the DSi.

The "i" in DSi symbolizes both an individual person (I) and the handheld's cameras (eyes); the former meaning contrasts with the "i"'s in Wii, which represent players gathering together. Nintendo of America president Reggie Fils-Aime said that, "If Wii was about gaming for the masses, then think of DSi as creativity for the masses." Iwata has said that the DSi is meant to be a first camera for children, and a social network

The DSi helped maintain strong sales for Nintendo's handheld product line. The DSi accounted for 40 percent of its product line's 2009 sales in the UK and frequently topped weekly sales charts in Japan during its first year of availability. In the United States, the console's initial three-month sales surpassed those of the DS, DS Lite, and Wii. The average weekly sales rate of the Wii and Nintendo DS declined slightly in March; Nintendo DS hardware sales stabilized to over 200,000 units for seven months after the DSi's launch, while Wii sales continued to diminish.

 estimated that, during October 2009 and February 2010, 50 percent of Nintendo DS unit sales were DSi consoles. In an October 2009 interview, Fils-Aime announced that the DSi had sold 2.2 million units in the United States. He said, "If you give the consumer great value in terms of what they pay, they're willing to spend, and we say [that] based on the experience of launching the DSi". The United States had its highest yearly DS sales in 2009 with 11.22 million units sold. The DSi and DSi XL accounted for 16.88 of the 27.11 million units sold worldwide of its product line for Nintendo's fiscal year beginning April 1, 2009 and ending March 31, 2010.

In a United States hardware sales estimate for July 2010 by Gamasutra, the DSi and DSi XL each outsold the DS Lite. The website also reported the DSi sold approximately 300,000 units in July 2009 and February 2010, which remains consistent for July 2010 if combined with DSi XL sales. As a result, the average price consumers were spending on the Nintendo DS hardware family rose to over $165 (in 2004 dollars, $ adjusted for inflation ), which is over $15 more than the November 2004 launch price of the original Nintendo DS. Nintendo made its first price cuts for the DSi in Europe on June 18, 2010, for the DSi and DSi XL consoles in Japan on June 19, and in North America on September 12. The DSi and DSi XL accounted for 14.66 of the 17.52 million units sold worldwide of its product line for Nintendo's fiscal year beginning April 1, 2010 and ending March 31, 2011.

In a United States hardware sales estimate for July 2011 by Gamasutra following the DS Lite's price drop a month earlier, about 60 to 70 percent of approximately 290,000 DS units sold were DSi and DSi XL consoles. The website reported DS sales for the following month decreased by 45 percent.

. The handheld features four lettered buttons (X, Y, A, B), a directional pad, and Start, Select, and Power buttons. Two shoulder buttons, a game card slot, and a power cable input are placed under the console's hinge. The DSi is 2.95 inches (74.9 mm) long × 5.39 inches (136.9 mm) wide × 0.74 inches (18.8 mm) tall (when closed), and weighs 0.472 pounds (214.1 g).

Brightness and volume controls are placed on the left side of the DSi; five brightness settings—one more than the DS Lite—are available. However, the console's battery life is shorter than that of the DS Lite, regardless of which brightness setting is selected; for example, the DSi has a battery life of 9–14 hours on the lowest brightness setting, compared to the 15–19 hours of the DS Lite on the same setting.

Larger model

The Nintendo DSi XL was announced on October 29, 2009: it features larger screens, and a greater overall size, than the original DSi. It is the fourth model of Nintendo DS, and the first to be available as a size variation of the same model. Iwata said that cost restraints had, until then, limited the screen size and multiplayer aspects of portable game consoles, and that the DSi XL offers "an improved view angle on the screens", which makes it the first "portable system that can be enjoyed with people surrounding the gamer." He argued that this introduces a new method of playing portable video games, wherein those "surrounding the game player can also join in one way or the other to the gameplay." While the original DSi was specifically designed for individual use, Iwata suggested that DSi XL buyers give the console a "steady place on a table in the living room," so that it might be shared by multiple household members.

With measurements of 3.6 inches (91.4 mm) long × 6.34 inches (161 mm) wide × 0.83 inches (21.1 mm) tall, and a weight of 0.692 pounds (313.9 g), the DSi XL is the longest, widest and heaviest DS model. The console features two 4.2 inches (106.7 mm) wide-viewing angle

 LCD screens with the same resolution as the smaller model. It has improved battery life over the DSi on all brightness settings; for example, batteries last 13–17 hours on the lowest level of brightness. The console is outfitted with identical speakers seen in its predecessor, but are contained in larger speaker enclosures, enabling them to produce louder sound. The hinges stop the screen at 120° in addition to the original DSi's position of 155° in order to allow easier viewing when placed on a table-top. The DSi XL is bundled with two longer styli, one of which is thicker, rounded, and pen-like, and does not fit inside the unit. Flipnote Studio and the Nintendo DSi Browser come pre-installed with the DSi XL, alongside other, region-specific software.

The DSi XL has a matte surface, and the exterior of its top panel is coated with a gloss finish. It is available in eight two-toned colors, but color selection varies by region. The white color is exclusive to Japan, while green is available in Japan and Europe. Red is exclusive to Australia and New Zealand, while the yellow color is available in Japan, Europe, Australia, and New Zealand. The pink color is exclusive to North America. Two special-edition models have been released: those for LovePlus+ and the 25th anniversary of Super Mario Bros.

s Joe Martin, and IGN's Harris and Lowe, believed that it was a reasonable exchange for SD card support and the DSi Shop. However, CNET's Bakalar stated, "We'd gladly give up the 4 millimeters [of reduced thickness] to be able to play any Game Boy Advance game."

Most reviewers criticized the quality of the DSi's cameras, particularly due to their resolution, which is lower than that of mobile phones. They considered them sufficient for the DSi's screens, however. Harris and Lowe believed that the camera's only use was to take "silly pictures of yourself and others". They complained about the difficulty of taking photographs in low-light environments, and said that even when such images were distinguishable, they were tinged green or blue.
