Found a very useful application for the iPhone this morning: Mocha VNC Lite. It lets you use the VNC protocol to control a computer. VNC is built into Leopard, and is available on Windows and on most flavors of *nix (that are using a GUI).
The application is free, and quite usable. The only hiccups I found were: 1) VNC seems to be a bit of a resource hog on OS X (as seen in the above photo), 2) I couldn’t find a way to scroll a window 3) I couldn’t find a way to move / resize a window.
None the less, it gives full access to the computer and, like I mentioned, it is very usable.
To do something that requires a single click on the computer, you do a double tap (like make a window the front most window, or launch a dock item).
The keyboard works well too. There is a “clover” key and a control key at the top of the screen (as seen above). There are no arrow keys, but the control key lets you do the Emacs bindings to move around in text and do “delete forward char” (ctrl+f, ctrl+b, ctrl+n, ctrl+p, etc etc).
Since this is the lite version I would guess that a more full featured version is on the way. However, Mocha VNC Lite, as it stands, is a very usable application and worth adding to your home screen.
(I’d really like to find an SSH application if you know of one)
