Good review, but i think your score was too generous. It's a complete rip-off of SSX 3 (though that was a rip-off of Tricky, apparently) with almost everything great about it taken out, lame menu screens, terrible customisation options, and music that's been borrowed from other PSP games.
I'm not saying the game is completely terrible but so much has been cut out that the game feels hollow, like things are missing. The only great things about it is its graphics (graphically, it's the best snowboarding game on a handheld, hands down) and being able to ski, but that's really it. I have to say, i was a little disappointed with it.
Btw, i wrote a review on this while i was away: i was gonna write it up on my PC tomorrow and post it up, but you beat me to it. It's okay, i'll post mine elsewhere: i know another site that's in desperate need of handheld game reviews.
