haven't really had any of that with the MT if any thing i find it much more comfortable to use the the mouse was.

have you tried one of the wrist cushions/pads that some used for the mouse ?

I noticed it a little at first but it has since passed. I found that for some reason I would be pressing and tightening up on some scenarios of using the MT. It's funny, but the more precision I'm trying to get with the cursor the harder I was mashing the pad surface (Yet not clicking). Hope that made some sense. I have found it comfortable having the MT toward the back of the work desk so that my whole forearm can sit on the desk. If the MT is to close to the front, having the forearm sitting on the edge of the desk seems to cut off circulation.

I have played with other MTs at the Apple stores and find some variation in their responsiveness to physical click. Some are loose and easy to click, others, like mine, no so loose yet. I find clicking at lower third of the surface is comfortable and somewhat effortless.
