I can't help but think that if there was a Venue Pro 8 with a decent dock so that you could use it as a desktop and take it to a meeting as a tablet would be just a no-brainer for corporate IT shops. I can't count the number of times I have seem someone running between meeting rooms balancing their laptop like a waitress running through a restaurant with a huge tray above her head. So, maybe a thunderbolt port for docking?
The short-term advancement I am looking forward is having my ipad mini and macbook air be a single core that can be docked a la Atrix and also become a full blown desktop on a dock a la surface 2 with gaming capabilities. Having it on a phone-size would be the next step but the 7 inch screen is so much better for reading.
There is the thinkpad Tablet 2 it has a docking station but I honestly find the build quality and functionality to be questionable at best. It also had issues connecting to my workplace wifi, I attributed it to Windows 8 but my colleagues surface pro did not have the same problems.
