Should I buy an air mouse?
For the past 5 years, I have been experiencing severe back spasms due to constant reaching for my mouse. I have bought ergonomic devices but those have not helped.
These air mice look promising. Although I have heard rumors that the mouse pointer on screen does not always align with the device being waived in the air. I hear it always need to be "reset." Is this true? Are air mice worth buying? The logitech one looks good. Does anyone else have any specific recommendations of air mice to buy if they are worth buying? Thank you so much.

I've been pondering on a Logitech cordless trackball mouse here. You can look over that model at http://www.newegg.com/Product/Produc...82E16826104125 Office supply stores charge something like $99.95 for that model!

The rf models don't seem to see the same problem of switching into 3D mode when simply going to lift the mouse up off of any flat surface. That was one comment in response to the review seen at http://gizmodo.com/gadgets/review/lo...why-285753.php
