i was thinking of the same thing of using Virtual Pc, but i have never tried sync or update. So i can only guess that it may work. Send an email to Virtual Pc and ask them, that might be the best thing
I hate the fact I spent over $5000 on my G5, and I can't even sync my Blackberry to it. I had to buy an old shi*box P3-800 for $50 and use that to sync over RDC.
