deskthority

I've been thinking for a while how to proceed my process of workstation minimization.
My current setup is still this:

The Datahand is made wireless with wireless usb and a big battery underneath the chair, so I can freely move about in the chair ...

Is it possible that it's not just the mouse that is the problem? What about a split keyboard and use shotcut keys? And an ergonomic chair would be beneficial too.
