I actually used to have one for a while - the HP mininote 2300. IT was fast, lightweight, had great storage, and actually had really good specs for something so tiny. I ran SuSE 11 on it and had no problems ever, other than my ineptitude with Linux.
I no longer have it due to some unfortunate circumstances, but I would definitely get one again in the future, when I can afford it. I don't need a laptop capable of gaming. I can just do that from my home computer. And I don't have the physical capacity to be able to carry a larger, heavier powerhouse of a laptop.
I miss my Mininote though, it was my favorite of all the computers I've ever had, and that's saying a lot.
Baa baa black sheep have you any booze? No sir, no sir, I'm a....sheep~
