9 should be good.
Remember, every other version of Windows is good.
95? Shit. Crashed all the time. 98? Awesome. Transformative. Amazing. Me? Shit. Crashed all the time. XP? Amazing. Transformative. Vista? Shit. Crashed all the time. And there were internal memos leaked that exposed the fact it was intentionally difficult and frustrating to use. 7? Amazing. Transformative. 8? Shit. Didn't crash all the time, but fucking Metro. And now all the settings are in two different places, and every time you try to find one it switches to the fucking Metro interface.
The reason Microsoft does this: It allows them to sell 2 Windows licenses for every PC OEMs sell. OEM licenses require OEMs to sell PC's with only the latest version of Windows, so the OEM has to buy one license for Windows 8, then another license for Windows 7 so they can ship Windows 7 as demanded by the customer.
