I'm very disappointed with my Surface Pro tablet ... battery life sucks, resuming from sleep is really slow and the keycover needs to be disconnected and reconnected for it to 'remember' it is there. I've owned 4 Surfaces over the years and won't buy again. I'm not a fan of OS X but seriously considering one of these just for the battery life and it-just-works portable computing.
