I just upgraded to Parallels 7. Not sure exactly what I am getting for my $50, but this made me unhappy. There is now a link for "Convenience Store..." directly in the Parallels menu when in Coherence Mode. Well, so they're already scalping me for $50 for the upgrade, and now they're promoting their own "store" where presumably they get a cut for every product sold? I'm upset about this, as it's a form of advertising. Advertising is fine in free software, especially when there is an option to pay to get rid of it, but I find advertising unacceptable on paid software (particularly at this price).
Convenience store, which might be convenient, as it allows you to buy Windows licenses and download Windows directly from the internet (only US and Canada ATM).
