Lack of indicator lights and ports
This has been a trend with all new Dells, and probably many other manufacturers. It used to be you got a nice, full complement of ports and lights indicating power, charging state, and hard drive activity at the least. My Dad used to lament the disappearance of gauges in cars giving way to 'idiot lights'. He probably would have had a lot to bitch about with laptops--now you don't even get those.
It would be nice if engineers would have a say in the design, and not marketing folks going for "the clean look", or whatever delusional thing they're going for. And I'd cheerfully pay an extra $50 for a laptop that had an extra port or two and could tell me what's going on internally.
This is especially a nuisance when a machine is getting updated--the Windows update process gives you scant information already, and without even a drive activity light to tell you what's going on, you just have to guess if the damn thing is actually doing anything or if you should hold down the power button and start over. And it sounds like the power button isn't very cooperative either.
