Will Windows Matter in 10 Years?

Yeah, that's pretty much correct, except for this, referring to corporate usage: "Because Windows infrastructure has been used and perfected for so long, I do believe they will still maintain a majority stake in 10 years."

That's rotting too. When those kids in college with 70% Macs go into the workforce, and are used to 1) everything in the cloud, 2) computers that actually work, 3) not being subject to the IT department for login problems, problems caused by malware, problems caused by anti-malware, Exchange problems, and so on, you think they're going to put up with Windows? In the last ten years of my working life, I've been at companies going from all Windows, to Windows + Mac + Linux, to a completely Windows-free environment. Even our marketing guys are on Macs and google mail/calendar. They still have Office on Macs, but google docs is displacing that quickly, because sharing Office docs sucks.

I think Microsoft experiences its first quarterly loss within 10 years.

The cloud is going to eliminate the need for Windows IT infrastructure. Who needs group policies when you run everything in the cloud?

To ask this question and start out completely discounting the corporate market is ridiculous.
