DISQUS

You have to measure to the bottom of the tabs, or the bottom of the heads up toolbar, not just to the bottom of the gray area.

About functionality, I mean that they have removed functionality that existed in 2007.

Oh, and the graphics stuff is only a benefit if you have a new card capable of taking advantage of it. I have two nice cards both about 1.5 years old, and they are both on the "not recommended" list (FX3450). For most users like me, the graphics are going to be a step backwards in performance. Mine looks good, but rotates like a Radeon.

Interesting take on the interface changes. I don't believe it is true that you have more space. That's something that can be measured. The new interface takes up more space than the old one, and more of it is blank. By putting everything on the CommandManager, there is more clicking to do.

The main things to me are the loss of flexibility and the problems with shifting back and forth between text and icons in the RMB menus.

Anyway, I do like the pop-up toolbars, but the S key won't benefit me much. You can have hotkeys directly to the functions on the toolbar, why have a hotkey bring up a toolbar from which you select something? That adds a step.

Once you look past the gloss of the shiny new interface, the actual functionality is less than 2007 in several areas.
