I think I will be getting one as soon as I can.
I finish uni and start work soon, so I am going to need something to keep me entertained on the train journeys to and from work. Plus some of my friends say they are going to get one and you can link 4 of them together apparently - and this is the best bit. Apparently you can link 4 of them together to play the same game off just the one cartridge. I am looking forward to it coming out over in the UK.
