Interesting, I didn't know about the double finger tap either.
Anyone messed with the sensitivity of the touchpad on the keyboard? I think the biggest problem that I have right now is using the attached keyboard, the cursor will jump to where the mouse is on the screen. That at least is the most often occurring problem.
After having it for about a week, I do like the suggestion about having a bluetooth keyboard if working in photoshop (I think I read that on here). That way you can position the screen where you need it, and still have the keyboard available for shortcuts (which I use all the time).
Also, do you guys always/often have more than one usb item plugged in? Other than importing pictures, the only thing I typically use the USB for is the wireless mouse.
Wish I had more time to goof around with it and get things setup on it.
EDIT: I also set it up to use the pin, but mostly because I am lazy like that. 4 digit pin with the on screen number pad is FAR easier to get in quickly than the "strong" password used for the Microsoft account.
