So, this isn't quite the mini-keyboard from Korg, but I guess there's a niche for everything. Form your own opinions. Ready, set...GO!

Yeah dude, I posted about that a while back when I saw an ad for it in Electronic Musican Magazine. It seems every kid at my school has either an iPod touch or a DS, so I'm sure it won't be long before I hear that thing all over the school!
It may not be a bad thing, anything to keep them interested I guess:)
