This new generation of Mac products under Cook have been terrible. I bought the new MBP with the touchebar, about 80% maxed out when it first came out to use at work in conjunction with my desktop in my office. It's on a ventilated stand and I use an external mechanical keyboard, because that was the only decent option at the time. I have a ventilated cover sitting on the keyboards; so no dust. It's been chugging along just fine, but the latest round of issues plaguing the MBP line has me concerned whether or not my extended Apple Care was worth my money.
Fortunately, I have a few employees of mine wanting it since I expressed wanting to jump ship, so I may be able to recoup some of the cost. Money isn't a concern; a failing product is. I needed OSX/MacOS to run some Apple specific only software but in the period since I've managed to find better Windows alternatives. I'll likely buy an HP Xeon mobile workstation AKA a big laptop and use that at work.
Say what you want about profit exploding under Cook, but the dude is a number's guy. His short stint at Compaq had devastating effects for a couple years. The fact is there's more product problems under Cook's helm. He is the John Sculley of the current.
