Today, I received mail from Parallels asking me to upgrade and purchase Parallels Desktop for Mac..... I purchased Parallels Workstation for my Windows XP machine...on which I run Ubuntu (Feisty at the moment). It's annoying enough that from all I observe, Parallels development is focused on Mac to the exclusion of folks like me...but sending me junk mail to purchase an upgrade for a product I don't own????? Come on! Surely you know who purchased which of your products, don't you? I haven't drunk the Mac Koolaid yet, and don't plan to either. I could've installed Ubuntu on VMWare Workstation and it wouldn't have cost me a dime.
