In my experience as a tech, the tech market ALREADY IS, a blue collar market.
I have no college degree, neither did my last boss, in fact only one person in the IT dept there did. My current partner never went to college, in fact most people I know in the computer market have no college. Or else they have an unrelated degree. On the upper spectrum you have more people with degrees, but then again Mechanics for Ferraris and Porsche’s oftentimes have degrees too.
As for Windows market share. I think I’d watch out for Windows to steadily lose share. Linux now outnumbers Macintosh machihnes worldwide 4-3. Macintosh’s market share has not shrunk in a couple of years. OS X is probably the finest OS out there on the market, it can run Windows/Unix/Mac apps all pretty well.
I think the two things you will see that will hurt the MS market is a more user friendly Linux which will start making a viable option for the workstation market for businesses to cut costs, therefore they will. Also as part of this, the compatibility with windows ports will become more and more seemless. When this happens, Windows will be largely irrelevant.
The second is OS X being released for PCs. According to rumors this port already exists, and why wouldn’t it? It’s just a marketing option at this point I would think. OS X is VASTLY superior to Windows, and a lot of people are switching to it in droves. If I could afford a laptop it would be a Mac and not a PC, then again, I’ve been doing Mac and PC tech support for years, so I’m not exactly the market that’s going to increase market share.
