Tools: Office Live
MicroSoft has released Office Live, or at least a version of it, to the public and it looks pretty good. In fact, it looks almost exactly like Office 2010 such that, were you running it in a frameless browser, you might not notice it was a web app. At least until you tried to print something (not enabled), or try to open a OneNote notebook (also not enabled). It comes with 25GB of storage, which is quite a lot for documents. It imports doc and docx well, unless tracking is turned on - that should be obvious but it's still annoying. Right now, I'd say it doesn't really bring much to the free cloud-based office-suite universe that Google wasn't already doing better, but like most MS releases, I suspect v2.0 to be a contender.
