I've bought this thing and its awesome with it's touchscreen and microphone

ive bought Mario (Very cool mini games with touchscreen.. lots of fun) and Nintendogs (this is the reason i bought nintendo.. u can have your dog, pet your dog, feed it, train it and teach commands with microphone, play with your dog and enter dog contests.. its a great feeling that my dog looks at me when i call him "Jim" )

There are lots of cool games for nintendoDS but games are a little expensive in Turkey..

I suggest you to buy this awesome console
