I like my Surface Pro 2, yes I have a keyboard and a mini-mouse to make it fully functional but comparing it to my ThinkPad I like the smaller footprint and easier to carry from room to room and do not loose any speed in connecting, printing, checking websites, logging into AC etc.
Yes it is twice the price of a laptop.
If AC developers weren't so busy with MU and other mandates and would write it to be touch screen/gesture compatible it would be a near no-brainer.
