Different thing. You don't have to keep perpetually paying the dealer to keep using your car. Sure you pay the bank because cars are expensive(why I'm glad mine is paid off), but you buy gas, or lets say programs for Microsoft Windows, from 3rd party vendors if you like. You don't have to be locked in. That's what is unfair if Microsoft charges you for subscriptions. I get office, but that's an extra feature. We are talking about the basic use of your pc, you already buy the product, so you tell me I then have to pay another amount each month to use a device I already paid hundreds for just because of Microsoft? If that is the path they take, I hope some Linux variant takes off.
I guess really we've never "owned" the OS, due to licensing, at least not legally, but in practice it's worked that way. If they do subscription, they may encourage software piracy, because how many people are going to be irritated because they are told they can't do something. Plus the economy the way it is, not sure people are going to go for subscription. I mean most of the computers we get in are still Windows 7, even some Windows Vista as people are afraid of Windows 8 and don't like Windows 8 and want to keep their familiar pc running. Most of the builds we do, people want Windows 7, not Windows 8. When we've sold a PC with Windows 8, many people want classic shell or a variant. Rumors are Windows 9 will be better, but what if they pull another Windows 8 and add a subscription? How many people are going to say iPad or Mac?
