Parallels, Bootcamp, and CrossOver for Mac

[Jun aka Pekto]

I'm currently using Bootcamp and Parallels... I tried CrossOver a little bit but still found it buggy... I'm running them on a core duo and core 2 duo machines as well...

anything you want to know about them?

Well for one thing, how's the speed/responsiveness of Parallels on a Core Duo?
If it's responsive enough, I'd probably stay in Tiger and use Parallels' Coherence Mode.

For Bootcamp, does XP/Vista see the Mac partition and vice versa with Tiger?
So long as one or the other can see files at the other side. I want to try and avoid duplication of files besides using external storage.
