Subscribing to MS Office - No
Personally, I would not pay $99 per year for Office. Believe it or not, I still use Lotus 2000 SmartSuite, including 123 and Word Pro. I also use Openoffice.org (free) and get along just fine. I would switch from 123 to Excel except that I have files that go back 10 years (some updated daily) and I don't want to re-format those.
