What's the difference? One is free with a $40 upgrade, the other is $99. I am planning to use this on my 3rd Gen iPad for my iMac and PC. If there is a better Remote Desktop Client (RDC) than these two? I don't really want to mess with port forwarding, etc. I just want to set it up, and have it work. I am more interested in speed and quality (obviously, I guess) so any help would be appreciated!
