Oh, seems I've been right - sorta
Paul Thurrott has some Longhorn ScreenShots too and describes it as .. well.. he hasn't got much positive to say:
I'm reflecting a bit
on Longhorn 5048. My thoughts are not positive, not positive at all.
This is a painful build to have to deal with after a year of waiting, a
step back in some ways. I hope Microsoft has surprises up their
sleeves. This has the makings of a train wreck.
Apple seems to gain quite some momentum, I hope they're able to deal with that.
