Using a portable wireless keyboard (connected by Bluetooth) to the iPad has made me learn (and think about) the implications of the “touch” interface. I began using computers in the 1980′s and, of course, interacted with computing devices only through a keyboard and a mouse. In the iPad, I am forced to interact via “touch.” It makes me realize that online research products for tax, legal and regulatory professionals will have to change. “Touch” as an input to a computing device introduces new opportunities for my employer to make professionals’ work more productive. I’m excited about the possibility and eager to hear any ideas you might have about how our products and services should evolve. Any thoughts?
