Microsoft Windows 8

Pros: It's less expensive than Windows 7.

Cons: It's clunky, non-intuitive for mouse-users, and not nearly as productive as Windows 7 straight out of the box. I want much finer control of my computer than I get with 8 Metro! I feel very restricted when using 8.

Summary: Long story short, for me Windows 7 is superior in almost every way to Windows 8 as far as getting work done. If this is the direction of Windows, I'm glad I own some Windows 7 boxes already. I develop software all day long. I cannot afford to fight with an operating system when I'm working. I have to move fast and have total control of the computer, and Windows 8 Metro just doesn't do it for me.
