A nice bit of MS bashing I see.
The drag-and-drop of task bar items isn't exactly new, people have been asking about it for years (it should have been in vista), hell all of this stuff should have been in vista. There are windows theme programs which I'm sure can emulate drag-and-drop already anyway.
For all those that moan about the Office 2007 UI change, it's the best thing that ever happened to office, people just don't like change. Once you get used to it (yeah it can be a pain working out where everything is at first and it does take a bit of time), it's just so much better than the old system, you wonder why it hasn't been around before.
