As an unwitting recipient of a intel duo iMac, (their mistake! ha!) I lost the ability to use VirtualPC, which i used extensively. Along comes BootCamp, followed within 24 hours by Parallels Workstation Beta. I am now on beta 6 of Parallels, and have not booted off my Bootcamp partition since the first time. Not looking back.
They're just getting the shared volume thing down now, but I really didn't need it, I just published a SMB share and networked to it from inside Windows.
BootCamp is an oddity, a POC. Concurrent virtualized systems is the future. (Just buy some RAM first) The joke is, how do I get my 15GB back from the BootCamp partition? Hmmmm, I wonder if SuperDuper could help me out there...
I can only imagine that SD has no trouble with Parallels container files, eh?
