Here’s something coming soon for the N900 (uploaded by sureshchande): an alternative to Documents to Go (30 days trial for viewer, plus I think there’s a paid editor version somewhere) on Maemo 5.
It’s useful just as an office viewer (if you don’t fancy editing). I often have to check over excel files, word, ppt, from my email and without such a viewer, would have to wait to get to a computer to read them. This way, you could just check on your phone.
(BTW, I can’t wait for Qt apps to be the norm so I don’t have to keep segrating apps available for one Nokia platform to another …Oy -_-)
Another free solution to editing documents on the go is with Google Docs. The N900′s awesome browser lets you use google docs. Just upload any files to your account and edit within the browser (not good if you don’t have a good connection)
(PS Happy 4th Of July/Independence Day American readers! )
