I really love the tunnelled VNC that iSSH offers. I use this a lot to get to my home machine. Also the keyboard and associated list of all available command and function buttons is really nice. I also like the "mouse" buttons. Those are very nice instead of tapping the screen which can be "fat-fingered." Nothing worse than choosing "close" instead of "save". I also like the fact that it works over 3G so I can truely get to my home machine anywhere, anytime.
