Dell
IMHO, Dell deserves a dishonorable mention. Not only has the quality of their laptop hardware dropped precipitously, but I discovered with my recent work-issued Precision that the battery is not readily customer-replaceable. This really sucks because the battery lasts maybe two hours on a good day, and that's with a reasonably new battery. Once it starts to degrade, I can probably look forward to the battery life dropping below an hour, and replacing it will probably be a nightmare of myriad tiny screws and possibly glue. People complain about phones, but the movement to non-swappable laptop batteries is a much greater crime.
