Dell generally have good computers indeed, well at least according to the little experience I have with them. My father has a Latitude which I use occasionally, and it seems to be very stable. He's more than happy with it as well.
These days I'm on a host of different computers, since all of my roommates have a computer (laptop, actually) each, and I've had some problems getting my own online through our network.
I don't mind all that much though, since all I really need to go about with my daily business is Notepad++ and an FTP program, both of which I've installed on all of their computers

Right now I'm on my a packard bell, which isn't really my favourite. But it does the job, really.
