Earlier quoted context omitted.
I don't know if there is a such a term or concept but I would put these companies or products in the same category: Motorola, IBM Thinkpad, Nokia, Sony Ericsson, Fujitsu computers
Lenovo has done a decent job with ThinkPad. I'm running an X1 Carbon and love it.
I had a T60 that had the both hinges snap in the case in normal operation, x230 screen broke and it refuses to start without reinserting the battery. I had similar screen issues with an x100e but at least that didn't have a quality persona around it, so I can't say I'm surprised.
I gave up a while ago and just use an iPad for everything (currently a student so I use the pencil heavily). If something warrants me using a keyboard then I just do at home with a tiny NUC I bought for cheap (HP EliteDesk 705 G2 Mini).
