It's a lovely bit of kit Adam, so I hope you'll be happy with it. When I played on GeekBoy's imported PSP I was almost moved to getting one around the corner at Memo (a white one of course, not because I liked the look but because at the time it was an assurance of getting a Japanese one (with a better screen)).
On the other hand one of Mark's colleagues bought a DS, sold it to buy a PSP, then sold THAT to buy a DS

- some people aren't so good at making their minds up

There are lots of reasons I haven't bought one yet, but that's mostly because there aren't any games that tickle my tastebuds, but when they release one, I expect I'll jump on the bandwagon, but it won't replace my DS
