Lots of Vapor haters will come out and complain about this board, but mostly because it's overpriced, not that there's anything wrong with it.
I currently ride a 2011 Vapor and had a 2009 version before it. If you will be riding mainly in deep soft snow or true powder then you should look elsewhere, more of a rocker shape will be better, ideally tapered.
If you don't get to ride such perfect snow, eg if you're riding groomed trails on the resort or off piste in less than ideal conditions, ie crunchy stuff that needs to be powered through then the Vapor is an excellent choice, I really like mine. It's a very responsive board. It does require disciplined technique to ride it, you can catch an edge much easier than on a rockered board, but its very fast edge to edge, carves really well, and jumps great, doesn't wash out on landings.
The one complaint is the price and if you've got a deal on one then that is not an issue.
