FreeBSD

Since I successfully managed to wipe my /home (by accident) and I don't care to recover what's on the HDD I'm considering trying out BSD.

So I have a couple questions if you don't mind:

How hard is the transition from Linux (Kubuntu and Arch) to FreeBSD?

Wine? Does it work well? How about the 64bit version?

amd64 instead of ia64 build for Intel DuelCore Duo?

Video drivers?

Thanks in advance!

(P.S. was advised to post here from /g/)

FreeBSD is a cool OS, but you have to want to use it.  The transition is pretty easy, but be warned: you start with a terminal, some ports, package manager of some kind, rudimentary programs (i.e. "it turns on and you can use vi"), a few man pages, and not much else.  You have to configure X11 and all that other stuff for yourself.
What's more, it's not well-supported by most companies.  Expect driver support and such to be sparse at best.  Still, it's a fine OS if you like *BSD.  The biggest difference between Linux & *BSD is the kernel.
