Here’s a hardware feature that doesn’t receive much publicity but which I’ve come to heavily appreciate: the Surface Pro’s AC adapter. The main reason is the USB slot on the adapter itself.
Whenever I travel, I don’t like carrying more than one plug converter and feel bad asking for more from the hotel — the USB slot on the power adapter solves that. The AC adapter charges the Surface and the USB slot simultaneously charges my smartphone, and it seems to charge just as quickly as it would normally.
Genius feature! If it gets shouted about enough, hopefully other manufacturers will follow.
