One OS or More
1. What MS really wants is to be Apple w/o actually telling consumers they have to buy into a closed environment. Instead they do this by trying to manipulate their flagship product, the OS.
2. The Linux market is moving in the correct direction; problem, no real money behind them.
3. A Windows Kernal should be the center to the MS universe. Everything else should be a "choice". Just like installing Server or even MS Office, have default choices Laptop/tablet/workstation/server etc. Each of these choices could also have their own list of options incl. interface, devices, services, apps etc. You should also be able to add or remove these services from the control panel at any time.
4. If you're going to allow people to program and customize, allow them to. Don't pretend to on one hand while tying to keep people married to you on the other. If you produce a better product, you'll keep the customers without the tricks.
