That said, I subscribed to the online MS Office suite (w/ SkyDrive and some other goodies) a few days ago and I'm impressed. The Microsoft user experience is pretty slick nowadays.
I've even switched from Google to Bing and Chrome to Internet Explorer for a month. At first the "newness" of it all was a bit jarring, like navagating an alien landscape, but after only a few days I don't think I'm ever going back.
Do yourself a solid and give it a test drive.
