Having used 10 and 11 interchangeably since 11 came out... meh.
I mean, maybe there are additional annoyances from the IT/sysadmin side that I just don't bump into as a user, but besides some UX downgrades that don't make sense (that taskbar... why?) it's a pretty neutral change. Maybe I'm to grizzled by having been there in the switch to 95. I unironically had Windows Me on my computer there for a while. I even caved and did some Vista eventually.
