As a little gift to myself I went and bought a Nintendo DS. Sssh it's not officially out until tomorrow.

The game I bought was Zoo Keeper, which is a puzzle game. You use the touch screen to move blocks of animal faces into groups of three or more. You have to try and catch a certain number of animals per level.

If you haven't captured enough of a certain animal, then their faces will turn angry. There will be the elusive one you can't find as the timer ticks away. Then the animals all start to shake making it even harder to find them! The machine itself is lovely. The screen is fully backlit, so SP games are much brighter. Stereo sound is also quite welcome. There is a stylus and also a thumb thing on the strap which is good for the demo FPS (Metroid Prime Hunters) which came with it.

There is a built-in mic, but the games which use it haven't fully exploited it. I hope some developers will use voice recognition in some cool way.

Wireless built in, so you can play against others who have a machine. You can also send messages in chat rooms if you have other DS owners around. Also there is an alarm clock and calendar. Go get one!
