Google Docs (Free)
If you use Google Docs a lot, you'll appreciate the tablet-friendly Google Docs app. It lets you collaborate with other Google Docs users; edit spreadsheets; view your documents; upload and convert files to the Google Docs format; take a photo (with your device) of printed text and convert it to a Google document; and easily share docs with your device's contacts.
