Not counting variations (though listed) and not counting embedded OS on devices I happen to touch (e.g. an ATM):

Windows (XP, 7, 2003/8 server)
OSX (10.5-7)
Linux (CENTOS, RHEL, Ubuntu, Gentoo.. others)
Solaris 10
iOS (if i can open an shell on my iphone it it counts!)

I'm a little confused by that, too.. unless someone's feelings were hurt because I said Gentoo is a pain in the ass to install, which is true. Heck, it didn't even support the onboard ethernet. Gentoo is my favorite distro, which is why I went through all the trouble to install it in the first place.

I still recommend the netbook remix. If, however, you want to try Gentoo I highly recommend moving the portage temp dir to a ramdisk to speed things up and minimize reads/writes to the SSD.

I use the ubuntu netbook remix. I have tried Xandros (default), eeeXubuntu (worked pretty well), and gentoo (pain in the ass to set up, but that's what gentoo is all about).

I recommend trying the netbook remix of Ubuntu. It's the one I have kept using the longest because I like the interface and it works well with the low resolution (I have an eee 701).

My favorite farewell letter was the one I sent out that simply quoted Monkey Wrench by Foo Fighters. I would ask my boss for information and he would just talk of of his ass because he was really quite ignorant (and a jerk). He would tell me I asked too many questions, and I would tell him he provided too few answers. It turns out a lot of my co-workers were big FF fans, so they really got a kick out of it as well.

One last thing before I quit
I never wanted any more than I could fit
Into my head I still remember every single word
You said and all the shit that somehow came along with it
Still there's one thing that comforts me since I was
Always caged and now I'm free
