This looks very nice. Switching to a split keyboard (Kinesis Freestyle)[1] and a trackball placed in the middle of the split so I can use it with either hand (pic of my current setup [2]) was a complete game changer for my RSI problems. It hasn't eliminated it completely but I am managing much much better now.

My only complaint with the Freestyle is that it doesn't have mechanical switches but it's still quite pleasant to type on imo.

What trackball is that? Does it have scrolling capability?

[randlet]

It's a Kensington Orbit and yes it has a great (smooth) scroll wheel surrounding the entire trackball.

I have the Kensington Orbit and a Logitech Marble. While I love the scroll wheel on the Kensington, I find that the left button requires a bit more force than the Logitech when clicking. No such thing as a gaming trackball?

I still miss the Logitech Marble FX (out of production) http://www.amazon.com/Logitech-TrackMan-Marble-FX-Trackball/...

But it would be a terrible 'center' trackball.

I use a Marble FX at home, they are wonderful. Hope it never breaks. At work I use an M570 which is also quite good (thumb-only trackball).

Interesting. My one complaint about the Kensington is the buttons feel a little flimsy to me. Not sure I could live with that Logitech without a scroll wheel!
