I'm intrigued by the wireless adapter, an accessory to an accessory, so to speak. I can see the use case for it that was shown in the Microsoft video, but I can also see value in it in everyday use of the Surface. The new two-stop kickstand helps a great deal with posture issues for taller people like me using the Surface on a table, but being able to remove the keyboard all together and change typing positions in an unlimited way is very appealing.
