Looking forward to higher transfer rates and such alongside the 3 modes, it would be pretty epic for a lot of devices to have it inbuilt just to transfer small files, even HDD's. You wouldn't think about the amount of times I had to stay rummaging through my bag to find the cursed USB cable just to upload a document to it from my laptop when it could be so much better if they just implement a small battery (like that used for the CMOS and Watches) to let you do just that through wireless connection. Extra brownie points if the battery recharges while the device is plugged in via USB.
