Windows Live Mail

My hotmail account has now been upgraded to Live Mail. Considering my invite said it could be two weeks and it only took a couple of hours, I am impressed with the signup speed.
I'm not sure what I think of it so far but it doesn't leap out to me as a "woohoooo!". It does have a fairly decent looking calendar with the ability to share the calendar to my contacts, passport holders or anyone who knows the url (which is pretty easy to figure out). The publication of the calendar is in realtime, with an error message returned if the publication is revoked so no loss of privacy there.
There is quite a bit of functionality missing that can be seen at the Beta feedback page but you get a LOT of functionality missing if you use firefox - the calendar and the contacts tab is missing.
