If you are a Mac user (and have more than one computer) you will undoubtedly be familiar with Screen Sharing between machines. In a nutshell that is what Splashtop Remote Desktop does. Except in this case it is for connecting your PC to your iPad so you can use your iPad as aremote viewer and controller for your PC.
Splashtop Remote Desktop for iPad, iPhone and iPod touch works with Windows 7, Vista and XP. All you have to do is to download the app from the App Store to your iPad, and also download a client app from the developer’s (DeviceVM) web site. Once that second app is installed on the PC you should be able to connect from your iPad to the PC.You are basically viewing, and interacting with an image of your PC’s screen so you can practically do anything on your iPad now that you can on your PC. This includes word-processing, Web viewing, playing games, videos and even (shock horror!) using Flash.
Here's a quick video shows it in action:
The app is available in the App Store for $6.99, and as I said, you have to download the desktop client for your Windows or Mac OS X. All can be found on the official site here.
