There are a lot of other flash browser apps that can be downloaded from the app store for a relatively low price. Rover is currently only for the iPad, so it is worth checking out some of the other apps.
Splashtop remote browser is one of my favorites. It allows you to control your computer directly from your device; you are actually using your own computer's browser. This gives you the freedom to access all of your files and software programs directly from your computer. One reason why I love it is because it works awesome with the interactive whiteboard. Instead of having a slate to control the board, students can launch the Splashtop app and interact from anywhere in the room! If you get a chance, definitely check it out.
