Surface Pro 2 -vs- Yoga 2 Pro
I'm in need of a tablet/ultrabook for office work on the move.
I need microsoft office and a full pc experience so I need a Windows tablet (android or iPad or windows rt need not apply for this one folks)
In practice I will be working on desks when I'm working away so being able to use it standing up or walking around isn't really a requirement. I do look at a lot if pdf's though do walking around while reading would be a bonus I suppose but not vital.
The two options I've narrowed it down to are both soon to be released products, the surface pro 2 being microsofts 10" tablet and the yoga 2 pro being lenovos 13" ultra book/tablet hybrid.
Based on the information available, which do you think is better for real world mobile office work? Both have been compared a lot in the comment threads of various websites with seemingly equal numbers of "I'm getting the surface" and "I'm getting the yoga 2 pro".
