I'm very soon off to the land of the rising sun on a gap year to work and explore and I needed a piece of tech that could:
1: keep me occupied when im bored or lost :/
2: be able to connect to the internet
3: play games
4: small and light enough to carry with me without any dicomfort
And with the psp-go I've found it... Had it 2 days and think its great! I had a white original psp when they were first released but I didnt get on with it, carrying UMD's was a pain and people always eyeing it up was also annoying, but the GO is compact without being small and I feel a lot more comfortable about whipping it out on the bus for a quick blast!...
It has a nice bright display, battery seems to last a good few hours and wi-fi works fine (downloaded gran turismo and love it, an awsome game for a handheld).
To sum up, if you want a truly portable gaming device then this is it. you can argue the iphone is better but its a dam sight more expensive and the games look nowhere near as good as the psp's.. I rekon downloading games direct is the way forward and well done Sony for having the bottle to do it (in my opinion it is the future of portable gaming).
My only problems so far is the games off PSN are kinda pricey, the web browser cache fills up very fast and game download times are very long, but its early days and I'm very happy with mine.. Glad i bit the bullit and went for 1 but I did demo one in my local video game shop before hand so if you can do the same i'd say its a good idea.
