I've had the VX6800 since July and I fucking hate it. It's slow. Programs randomly turn on by themselves. It locks up for minutes on end. Volume sucks. Battery life sucks. Intrawebz is ok, but nothing great. Can read forums, but can't post.
Granted, I'm still on WM6. I should probably upgrade to 6.1 since you're saying it's much better. I also need to get off my ass and do some upgrades/downloads for it to see if I can make it tolerable. The dialer pad drives me nuts! Buttons are entirely too small.
I might mess with it a bit during winter break. If I can't get it to my satisfaction, I'm taking it back and bitching until they give me something else.
