First of all, I read on http://www.microsoft.com/mac/howtobuy.aspx?pid=sysreq that VPC for Mac is not working on Tiger yet? Is this true? Also, what are the RECOMMENDED system requirements for VPC? Like, what do you guys think is an appropriate Mac to use the VPC on in order to at least make it USABLE and not making me stare at a screen, waiting for the mouse to move? Thanks!
