Query: Excellent Design

Nintendo is brilliant. This compact piece of metal is quite a gaming system. It's very easy to hold, the screen works great, and the rechargable battery is amazing. Being able to fit this in your pocket is probably one of the best features. If you haven't upgraded to Gameboy Advance yet, and you're deciding between regular GBA and this, go for this!
