I too agree that Virtual Box is better than VMware generally speaking, but
this DOES NOT (in my opinion) hold true if you are using a windows host.
VBox seems to have a number of stability issues on window that makes it
quite risky to me if you want anything reliable. While VMware is a bit more
of a pain and a little less "full featured", it is a better option to run
linux on Windows as of 2009 when I last updated it. VBox is constantly
crashing, locking, and "faulting/erroring" when I try to restore from a
saved or paused state. I've tried 3.x and 4.x versions on XP and Win7,
respectively, and had similar results.

fwiw, setting up shared "network" folders is another way to go about sharing
data between the guest and host, and if you have VMplayer instead of the
paid version, maybe it is the only way?
