Wondering if there are any plans to release a mac client, so that i could for example view my windows PC on my Mac, in the same way we can on the iPad.
This is already sort of built into OS X - in Finder, just hit command-k, and do vnc://hostname. Access adds a lot of tablet like controls - goes far above what a normal VNC/RDP client can do - but they're all really tablet-relevant. I think having a parallels access client on the mac wouldn't give you any more functionality than the OSX build in vnc client.
