Now then, Harber, old son, here's what you need to do ...
In your laptops, get rid of the rubbery chiclet keyboard and use proper keyboards instead, like there are in most/all of your laptops prior to, and including T420 Thinkpad. See here for an example of what you need http://techdadreview.com/2011/09/15/lenovo-thinkpad-t420t520-laptop
If you do that, then people will be beating a path to your door!
You know it makes sense.
