I have a Thinkpad that I run as an FTP server and a Latitude D620 that’s my main machine.
Thinkpads are the most durable laptops I’ve ever seen - I just can’t break them.
The Latitude is good, I’ve dropped it a few times onto the hard floor in my apartment and it didn’t faze it.
The only thing I don’t like about the machine is issues with the hinges - they come loose frequently and I have to tighten them. Also, the left hinge actually wore through the metal bracket from opening and closing the lid - one day it just snapped off, and was the thickness of pop can aluminum. I’ve a feeling it’s an issue with my particular machine only, though.
Over all, I like both of them.
My mother has an HP notebook, and it does give her issues occasionally. Also, the screen is so awkwardly hinged it drives me nuts, so I personally avoid them.
Your budget is the biggest factor though.
