That would be a productivity improvement not having to keep relocating the right hand to operate the mouse. I never got good with the thinkpad nub..
Its possible I am.
But its exactly how I felt after sitting in a chair I spent hundreds of dollars on. I guess I just expected more for the money but perhaps my expectations were too high.
In an effort to create more jobs, my employer hires people to be our office chairs. Desks too.
It's good to do exercises to improve core strength too. Greatly helps in avoiding back problems.
I found this out the hard way when I broke a rib; resulting in a lot of lost core strength. I ended up in a great deal of back pain.
One person at our office has a secret labs chair and i find it way way too firm
I also have a Herman Miller Aeron and absolutely love it so much, I bought one personally for home.
