I'd agree with the comment about ACER. We had about a dozen. Only one survived the first year. No common fault - just poor build quality. Generally, Dells have been good for my company although they seem to have lost their marbles with the new Dell Precision. Very ugly for an expensive laptop (unlike the model it superseded) and on the larger screens a power supply like a brick (literally!). Toshiba and Fujitsu seem to be reliable.
