You are free to be surprised all you wish: I went back to linux because I was sick of dealing with the system locking up for 5-10 seconds every time I opened, closed, or switched to a new browser tab. Couple that with 1-2 fewer hours' worth of battery life and I found myself very quickly asking what the point of "code correctness" was if the system just doesn't work.

A thoroughly frustrating experience from top to bottom.
