sorry to bring up this topic again, but I recently have been experiencing some RSI symptoms and I have a couple questions:
- to the people who have simply switched mouse hands (right <> left), how do you deal with your keyboard? Do you still use the modifier keys on the left side, or do you switch to the right? if you switch to the right, what do you do about undo (cmd/cntr - Z) copy, paste, select all, redo etc... ? 
- to those who use a tablet, do you find you still have the same functionality as your 3-button mouse? I rely heavily on mouse buttons, especially for general camera navigation in C4D, and am concerned because the stylus only appears to have 2 buttons. Also, no more scroll-wheel, correct? 

I use a Magic Trackpad. Once you get use to the gestures it's hard to use a mouse. I also have a Wacom tablet for those times I need to use a stylus. The combo works great for me.
