This post from Fake Steve Jobs is hilarious because honestly as soon as I saw the images from the keynote, this is what I was thinking. The logo is scary same. You don't forget an OS that shitty.
I did the 60-day .mac trial and thought it was worthwhile. I haven't bought the subscription yet, because I knew something else was coming. I will probably buy MobileMe, because it solves a problem that I deal with - namely synchronizing between multiple Macs plus a phone.
FYI, the office freak out you posted was a fake:

I could tell it was fake because when the guy throws the computer at the girl she is bracing herself like she is expecting it.
