The iPad might not be able to do everything a PC can do, but with this app it comes close to it. For $11.99, you'll be able to view and control your desktop or laptop just like you were sitting in front of it. Use it to access files or software, or even just to get Flash support, which the iPad unfortunately lacks. It's compatible with both the RDP and VNC protocols, supporting Windows, Mac, and Linux computers. Currently, they're working on updates for better 3G support.

If you use the web-based Google Docs apps to create or share documents, this one is for you. Google offers a mobile version of the site, but this app gives you a better GUI and more features. It supports local documents, offline viewing, revisions, e-mailing, and Wi-Fi sharing and uploading. If you're an avid user, the $3.99 price is well worth it.

Unfortunately, the iPad doesn't let you work with office documents right out of the box. If you're an Apple fan or Mac user, you've probably heard of iWork. If you haven't, it's Apple's office suite, much like Microsoft Office. Well, three of the apps have been designed for iPad: Pages (word processor), Numbers (for spreedsheets), and Keynote (for presentations). Each can export to the appropriate Microsoft format or as a PDF. You can purchase them for $9.99 each.
