Can the SP3 pen be used as a non-drawing stylus with desktop apps for more precise control in icon selection than one would get from their finger? I would like to use the SP3 at home in an easy chair as a tablet without a keyboard, touch pad or mouse. The software is specific for the healthcare field and was not designed for a touch interface. I'm hoping the SP3 with pen input will allow me to do some work at home, from the comfort of a recliner.
