IMHO, giving a new stud the ability to use a tablet is a freaking horrible idea. Learn first how to orient yourself the old-fashioned way. Then when you've proven you can't get lost, you get to use the Gucci stuff. I didn't get to use GPS/INS waypoints on a low-level on either of my trips through flight school right away. Rightfully so. Should be the same with tablets. If I were king, I'd say you're allowed to use them in the brief only until you've passed some checkpoint in the syllabus such as an instrument check or the old VT-86 COMP-5X checkride.
As much as the harassment package sucked, parts of it made you a better aviator. That said, the rest is just harassment, and F any instructor who doesn't know the difference.
