Has anyone used or even tried the on-line versions of Word or Excel? I've been using Outlook.com to communicate by e-mail with my late wife's family in South America ever since Hotmail was absorbed by Outlook.com, but I've never explored anything else in Outlook.com. I was poking around, trying to find a way to back-up e-mails (and not finding anything) when I stumbled upon on-line versions of Word, Excel, and Powerpoint.
Any good? There has to be a catch -- are they free to use, or is it a trap? What's the scopp?
