Rank your favorite OSs

Let's get nerdy with it.

Even though I haven't used every operating system ever, I have used alot and here is how I rank them. I threw some mobile os's, server os's and desktop/notebooks.

1.) webOS

2.) OSX

3.) Windows 7

4.) Windows 8

5.) Red Hat Linux/CentOS/Fedora

6.) iOS

7.) Windows XP

8.) Android

9.) Ubuntu/Debian

10.) Windows Phone

What are yours?
