I dislike technology. Only in 2005 did I reluctantly shift from using transparencies to computer slides. But the tablet enables me to go backwards in time. Now I can use a pen, see my own handwriting appear on the screen, and update the content of the slide during the lecture as I see fit. Soon we'll be able to do without mouse or keyboard altogether. I am thrilled!
Current students, however, might not be so thrilled since they grew up with keyboards and do not resent their presence, so there is only a small window of opportunity for tablet development before the pen-loving generations disappear.
Next goal: when will we go backwards to the time of my beloved fountain pen?
