Surface was originally a large tabletop device for multiple users and I believe there were also wall units something like weather people use.I also wouldn't mind 'the hard cover' lol, made from the same material as the Surface that indeed, locks it. Okay, I'm basically looking for a Surface laptop... but there certainly are cases where I do like to remove the keyboard.
I wouldn't mind seeing a smaller bezel, and... the bloody Windows button moved back to the centre!
Regarding to anything Surface related, I want a 32-46" Surface TV set much like Google will be getting Sony to make with their Android TV sets next year. Man, that'd be a beautiful device, although I guess it would go against what the Surface stands for which is touchscreen.
