If you can’t crunch numbers based on Nintendo press release, and need to compare visually how significant is the size upgrade, then you would need to check out the video.

I ‘m thinking that the new size wouldn’t be a hit with the younger folks since its too huge to fit into your pocket.

The new DSi LL will feature a much larger touch screen which is similar to the PSP Go, and it will be released in new colors for the casing. Here’s a photo comparing the new DSi LL with the DS.

And if you were wondering why Nintendo decided to release the DSi with a larger screen, one of the reason is because they wanted to target the older population who might have trouble seeing on the tiny screen previously ^^
