Windows 8 is not unusable, but it is a mess, and I hate it. I hated the Metro interface with a passion when it first appeared on my AdBox 360. It makes no sense for a desktop PC. I will never, I repeat, NEVER replace my PC monitor with a touch screen. Windows 8 is an inept attempt by MS to push hardware sales and possibly to drive their stock price down for a buy back just before announcing Windows 9. I'm upgrading my PC with a Samsung 840 Pro 512GB SSD, and I'll be installing Windows 7 on it.
