I was recently forced to switch to a Mac for work. After 6+ months I am still relatively unimpressed.
I feel like such a big baby, and I know it's because I am familiar with something else, but I cannot express enough how much I hate Mac's window management. I constantly have to split up my work between multiple Chrome windows and I am now resigned to losing track of everything all the time.
(Hardware wise - I might actually disagree. The device feels nice, but I've found it to be fairly fragile and delicate. Whereas you can drop a Thinkpad down a flight of stairs into a pool of ice cream, a 6-inch fall onto a hard surface might total the screen on the MacBook. But special shoutout to the speakers which still impress me.)
