nathan: try PB Tech they have a bunch of the Wacom pens in stock
No luck with PB, Microsoft should work on a pro Wacom pen for creatives, that is basically Wintab compatible Intuos 5 grip pen.
Two buttons, and an eraser with rubber grip - with the tips being the regular wacom size for easy replacement/compatibility. This device has a lot more potential than just sitting in the boardroom.
You could also sell a 'Wacom' screen protector, that recreates the feel of the Wacom Intuos surface while protecting the screen.
