If you've ever thought about buying the Splashtop Remote app for your iPad, today should be the day!??
The price is normally between $15 and $20, but it is on sale for a limited time for only $1.99! The server program that runs on the computers that you'd like to view/control is and has always been free, so this should be a no-brainer buy.
This is probably the best app that I've used for interacting with my laptop remotely from the iPad. Works great over wireless, and is very responsive.??
You can't go wrong for $1.99 – give it a try!
