Generally no.  Desktop usage involves lots of large rectangles, which
we handle well.  And I won't tolerate the kind of laziness I see in
the DDX modules for some graphics chips.  We damn well will accelerate
zero-lines that are long enough to benefit from it.  There are
multiple ways to accelerate text.  We'll have a real hardware cursor. 
There's no excuse for accelerating only solid fills and bitblts.

Doom 3 uses the GPU in ways that are completely different from how the
desktop (regular 2D apps) does.  But you might get good performance on
a AGP bus.

Better in some ways, comparable in others.  Generally, we've
implemented the most important parts of the OpenGL spec.

Basically, although profit does often go down with volume sales.

I hope some places will distribute it.

Well, the basic stuff isn't a problem.  It's just certain kinds of
priveleged bus accesses.  We'll let the hackers tackle that after
we've gotten the usual ones finished.  :)
