Hi -- I'm customizing my Wacom Intuos4 tablet for use with Aperture, and am looking to set up a very small working group to hammer out a couple of good full customizations (the pen has two switches and an eraser, and the tablet has 8 buttons and an iPod-like TouchRing™ -- a lot to customize). I have posted
a full message w. links on the Apple Aperture user-to-user forum -- please take a look and reply if interested.
The tablet, btw, is fantastic.
