I never had to buy an own laptop. I use those I get from my company for working.....privately I actually don't need a laptop for myself...I rather use a PC. ATM I have got a Lifebook E from the company where I work....it's a good one. Well....I don't have a special favorite, but I can tell you what I would not buy....and that's Dell and HP. Perhaps I'd buy a Thinkpad X1 ATM (if I should need)
