Nintendo's DS Lite Versus DSi by the Numbers
Nintendo's new DSi looks a lot like the DS Lite that was launched two years ago but there are some differences. Here's a comparison of the specifications of the two devices:
Screen: The DSi screen is 3.25 inches diagonal width. That's bigger than the 3-inch panels on the DS Lite. Both are color TFT (thin-film transistor) LCDs (liquid crystal displays) with 260,000 pixels resolution.
Size: The DSi measures 137 millimeters by 74.9mm by 18.9mm making it a little longer, deeper and thinner than the DS Lite, which measures 133mm by 73.9mm by 21.5mm.
Weight: The DSi weighs in at 214 grams. That's a touch lighter than the 218-gram DS Lite but close enough that you're unlikely to notice.
Battery life: Depending on the screen brightness gamers can expect anywhere between 3 hours and 14 hours on the DSi versus 5 hours to 19 hours on the DS Lite.
Battery recharge time: Good news for gamers is that the DSi takes 2 hours and 30 minutes to recharge -- 30 minutes faster than the DS Lite.
Compatibility: The DSi can play software developed for the DS and DSi but lacks the compatibility for GameBoy Advance software that's present on the DS Lite. Any DSi-specific software won't play on the DS Lite.
Inputs: The DSi features a DS and SD Card slot. On the DS Lite you can find a DS Card slot and GameBoy Advance cartridge slot but no SD Card compatibility. Both have connectors for power and a stereo headphone and microphone.
