Ugh the trackpad that doesn't work when too hot, the constant fan noise, oddly specific hard drives. I've had to fix Macs. I have an entirely different experience, except the battery life which was generally okay depending on what one was doing. We just had insane WiFi issues, screens failing, and tons and tons of fan noise complaints. It wasn't worse than Windows machines but it certainly wasn't better. The aluminum was nice though because it prevented a few cracked screens.
