Well I did go with the Surface Pro 2, like that it is a full version of Windows 8.1 professional, figured it was time I delved into touch screen functionality. Screen size is right at the borderline hurray for bifocals. Been practicing with the pen this may become my preferred input method.
Now have to decide do I load AC 6.6.1 on it and all my office computers or stay with 6.3, a chore for the weekend. Likely will just go for 6.6.1 will leave a few updates re: the experience and is it an improvement in flow.
