People don’t quite realize how popular the Nintendo DS really is. Sure it’s great for raising your brain age and playing with virtual puppies, but seriously, people love this thing. Since its release, the DS has sold over 77 million units worldwide. And how much do these things cost? $150? Do the math and you’ll see one of the reasons Nintendo has the highest profit per employee of any company in the world.

Now with the unveiling of the DSi, they look to cement their dominance one step further. The DSi is 12% slimmer than the DS, can play music, has bigger touch screens (3.25 inches), two built in cameras and SD memory cards for storage (no word on how much storage though). It’s not technically supposed to “replace” the DS, but I remember them saying that the DS wasn’t supposed to replace Gameboy Advance. And the fact that you’re asking “what’s Gameboy Advance?” would prove my point.

The DSi is set to be released November 1st, giving it plenty of time to sell out so you won’t be able to find one for Christmas. If you speak Japanese, you can go to the new DSi website here to learn more.
