I have a samsung qx410 and it is actually of pretty nice quality, and has a good keyboard my only complaint would be the touchpad but most of the time I have a mouse connected or am not using the mouse.

HP is absolutely the worst laptop brand I have ever owned, I've known plenty of people with HPs and almost every single laptop has overheated to the point of shutting down the computer and breaking within a year and a half.

Thinkpads have the added feature of being pretty compatible with linux, though I think some of the nvidia cards that come with the T series are not compatible yet.
