My vintage Palm TX can edit MS Office files - Word, Excel, PowerPoint (with Quick Office). It wasn't in the least slow. The N900 is more powerful Personally, I don't have enough need to view Office docs to pay for Quick Office. If there was a version that would edit files as well, I probably would buy it. But, until then I'll manage without (Google docs works pretty well for occasional use). I'll pass on the tea and sandwich for now, thanks..
