As to whether W10 will be a success, IMO a resounding YES.
this one from Wacom and designed with CAD in mind...it's £600-700 though. This one has accuracy down to 2048 pressure-steps pen sensitivity so you can get pretty fine lines and alterations. Cheaper ones will probably be too coarse for you. Google ' intuos 4 xl cad youtube' for videos of it to get an idea of its capabilities. If you want to look at Wacom's other range just Google ' wacom intuos pro'
I've got the enterprise edition --it shows ENTERPRISE edition clearly in the Winver command popup and an expiry date of OCT 1 2015. His doesn't say ENTERPRISE and it's Oct 02 expiry (Torrent / leaked build / insider build ??).
