The main problem as I see it is windows kept it's cards so close that no one wrote any drivers for it, still no one seems to wants to write drivers for vista. I dis-like MS as much as the next guy but other companies should be picking up the ball for drivers.
Vista has been out for a while, why the hell should drivers not be out for common products is ridiculous. ie Graphtec, sign warehouse vinyl express, A new windows OS is out, maybe software/ hardware should get off there a$$ and do some coding for it.....
That being said vista is a memory HOG, RUNS SLOWER, but it is pretty.
