As far as Office suites go, the iWork apps on iPad definitely cover everything most users need. I've had no problems creating documents in Pages on iPad and submitting them to my college which requires everything in Word format. The first couple times, I doubled checked and made sure the exported file looked fine on a computer, but now I just send them in directly from iPad. It's worked great for me, and I think it'd cover what most need from home and even business use of Office. The iWork apps are easily some of the most feature-rich on iPad.
