Slate.com’s Michael Aggar goes to town on Apple’s online guided video tour of the iPad, but he does bring up one valid point, albeit, in a very snarky way. If we use the iPad for productive stuff by employing the iWorks apps, where the heck is the port to hook it to a printer to get a hard copy or at least a USB thumb drive to transfer the files to another computer? I may have missed something in presentations, but I didn’t see  any ports on the “Verizon” 4G prototype I played with in December either – the question I had was, how do I print the photos I take on the iPad (this had a camera) and what if I wanted to transfer them to my MacMini? Maybe the iPad will be the end of hard copies and thumb drives?
