Yes, but the Power Cover with backlit capability would be just swell.
Re: Battery life, I posted somewhere as soon as I reached my destination after a 9 hrflight (of which 5 hr 30 mins was spent on the Surface working on a Word document + on an intermittent Chess game with default power settings) + 1 hour 30 min drive to the departing airport + close to 2 hours in a departing airport + 1 hour in the arriving airport + 20 min car drive to the hotel and with the device in "flight mode" all the time, the battery icon read 76%.
On arrival, I quickly connected to the hotel WiFi (unlimited and free, btw!), went for a shower, had a meal, had my first meeting for about 2 hours, worked on some mails, revisited the Word document I was working with on the flight, surfed the nets (reading this forum, among other things) - all of which took another 6 hours or so, and I was down to 34%, which is when I plugged the device in for charging. Note that post arrival, the device was no longer on "flight mode"!
By my reckoning, not too bad!
