Oddly I found the kickstand on the Surface Pro irritating to work with because the device becomes impossible to use on your lap, as you need to put the Surface quite far up your leg, and then the kickstand is further along than the length of your leg (hanging over your knees). So it becomes impractical to use.

The OS has done quite well to optimise battery I thought - App Nap has been great. If I reboot my MBP into Windows (so same hardware, different OS), I get worse battery life.

Agree with the ports - the Surface Pro I use at work has 1 USB port so plug in a wired mouse and you can't plug in your USB key. Despite the love of wifi, ports are a great way to keep your device useful.
