I'm using a Fujitsu Lifebook loaned by the school.
It's probably one of the best laptops I've used. Last year we had Toshibas, they pretty much imploded after a few months of usage, especially since we had to move around a lot in school between classes.
To top it off, the 'tech guys' at my school are vegetables. They seem live by the word: "REIMAGE", which wipes the laptop and re-installs windows. Even if you got a pencil through your monitor, they'll re-image it, give you a 200 dollar (AUS) insurance job and give you a new screen which isn't even compatable, thereby making the whole thing redundant. They also seem to hate Firefox, but one time when I told them about it, they showed me something on Internet Explorer and it crashed on them. I simply said:
"I rest my case."
And that's a huge reason why I take good care of my laptop. I'd rather fix it then the vegetables at the office.
