To be honest I, like many others, am not very keen on purchasing the next iteration of Windows. For me, XP was the absolute peak of what Microsoft could accomplish. Sure, it was buggy at first, but subsequent patches solved that those issues and turned the operating system into a product that was thankfully free of the myriad of problems with Windows ME. Vista's unreasonable content-restriction features were a real turn-off for me, and in my mind installing such features for the sake of the protection of intellectual property--given how flawed our concept of IP is--is insufficiently demanding on the patience of end users and generates results which are, at best, unreliable, and at worst nonexistent.
On top of that, Vista didn't offer anything new. Sure, there was DirectX 10, but given how huge the compatibility issues have been for quite a lot of games even that bonus is dubious. It offered a shiny new interface, but for the non-geek userbase--I.E., regular people whose knowledge of computers is limited to typing and pointing and clicking--there is nothing. New. It's got a shiny new interface, but at the end of the day it feels like XP bogged down by antipiracy firmware and the stability of a two-legged dog on stilts.
I am not anticipating Windows 7 to be any better.
Sigh. It's Sh!t like this that makes me want to switch to a Linux distro and just run everything I have with Wine.
