Couldn't agree more. However, I work for a a mega bank, and we are migrating to Vista over the next year. When you are dealing with tens of thousands of machines and thousands of applications, you HAVE to test. About 85% of everything works. That's still not a 100% however so its a major task.
That's why I find it hilarious when people take about migrating that many machines from Windows to Linux. It would take forever to any ROI on that if ever.
For the average home user though its a lot easier. That said, the average home user probably doesn't NEED Vista. But it is overall a more solid OS and on new hardware mainstream hardware, performance isn't an issue.
Yeah in hindsight i guess forgot to mention proprietary and custom software for businesses and such. Really though this thread is about the consumers perspective on vista and how warped it has become by people that really have no idea what thier even saying.
Businesses for obvious reasons work very differently when it comes to thier software and migrating.
As for migration to linux the big difference is if a business wanted to migrate to linux they would have a whole community willing to help make the transition as effortless as possible. It would suck at first but for alot of companies the cost difference and community makes alot of difference.
