I am putting on about 1000 mouse miles a day.  I'm getting some nasty joint pains.  Have you any experience with the touchpad and SolidWorks?  I'm using the Logitech Performance MX and except that the buttons are well placed, and overall comfort is accepatable, the pointer still isn't quite precise enough to grab the vertex or edge I'm targeting 100% of the time.

So, combined pain and mouse jitters, I was looking to possibly change to the pad.  Your advise and opinion is appreciated.

Thanks

Carter
