What kind of computer that you use this site lot?

My operating system is Windows XP on a desktop computer. I sometimes use different computers, but this is my default one, so long the video driver is working properly.
 
I don't really have a default, as I can either work on Mac OS X, Linux, BSD, Android, iOS, or Windows, in completely random order.
 
I use a Windows 7 PC laptop.

And she uses it on an Acer Netbook
 
And I use this computer with an F in a bubble for a logo. I'm not sure what type it is, because I never used it before. Does anybody know what kind of brand this is?
 
I think it's Fedora Project or something, but I'm completely unsure about the operating system.
 
I think she means Fedora, the community version of Red Hat Enterprise Linux.
