That graph is by incident, to make it meaningful you'd have to normalize by distribution. In an absolute sense Nvidia caused a lot more driver problems than others but if you don't weigh that with the relationships between the number of installations then it's hard to say that the problem was an Nvidia problem or that there are serious issues with the Vista driver architecture because all manufacturers had these issues.

I'm not current on the relative distributions of say Nvidia vs ATI, but all the machine here have either Nvidia or Intel graphics in them, not a single ATI one.

Don't forget about creative's sound drivers and such.

MS is doing the right thing. They showed Windows 7 to the world for a year. Gave people public testing (to get ppl excited) and now are doing major stability tests before release.

I heard wonderful things about Win7. So honestly its a good thing. About time MS got a kick in the shin about making shitty operating systems. If they bounce back, they are a good company, and I don't doubt they will. Apple can't ride the "cool" wave forever.
