I was looking for Office2HD for a friend who just got an iPad without success. Apparently it has changed it name to Citrix ShareFile QuickEdit and it's currently free (for a limited time?). I recommend it, solely due to the ease of editing and saving Dropbox files (seriously, if you don't use Dropbox or some other cloud thingy for your documents, do it! It's free too!)
It's free, so there really is no reason to not grab it (unless you don't have an iOS device).
If you don't have Dropbox either, I have a referal link that scores you and I an extra 500mb (not much, but I'm not complaining).
What an awkward name.
