I have just installed iSSH this is a powerful SSH/VNC program and so far I have to say it works really well. I was tempted to try prompt but the thing that swayed me over to iSSH was the ability to use screens. Prompt appears to look better but wasn’t as powerful prompt was only half the price.
I have installed Office² HD for iPad this allows you to open, view and edit Word Excel and Powerpoint files. I am using it with Google docs files and it works a treat.
