Twenty years ago I tried to use a touchpad, but I had a bad experience. My palms selected and moved directories and brought our production system down. Since then, the first thing I do on every new laptop is to disable the touchpad. Therefore, a touchpad is nothing but electronic waste for me.
Since that time, I have become addicted to the pointing stick keyboards. At present, this limits my options for laptops to Dell, Lenovo, and HP business class laptops.
Will you have configuration options for people like me? A keyboard with a pointing stick and/or the ability to forego a touchpad all together? I suppose I can try to use a finger trackball mouse. Any other suggestions?
