I wonder if the SP3 pen is a new model that Ntrig haven't supplied for other devices, and perhaps it needs a new driver.
Anyway, I'm not concerned by who exactly is the hold up, what I'd really like is for someone at Microsoft to at least acknowledge if this is being worked on and if so, what's the likely release date.
I run a game development studio and I'd like to get Surface Pro 3's for my artists to use with Mudbox and Photoshop, but I'm holding off on that investment until I can be sure the pens will work properly, the same way their current wacom tablet pens do.
Please, Define work properly. To me my pen work properly.
