I've been using the 64 bit beta for a while and more recently the RC.
It works well, no crashes. However if you have a device that doesn't have a Win 7 driver then you can use the one that works in XP, unless you load the 64 bit version of Win 7. Doh... :doh:

I thought XP was OK, except it wouldn't hibernate reliably. Win7 seems to do this just fine.
