Actually it's the Wacom (Bamboo) stylus for the iPad I'm after, not a stylus for the Bamboo grapahics tablet.

Just what I was looking for. The Bahnhofstrasse shop is perfect for popping in on the way back home. As a bonus they also stock the Adonit Jot Pro. A touch more expensive than online (but Digitec is out of stock anyway), but then again there is a the overhead of a store and I'm just happy that I can go and buy *today*.
