Do I Perhaps Have too Many Electronic Gadgets?

Which of these should I take to Berkeley for the first day of the semester today:

iPhone (for communicating).

iPad (for taking notes during pointless bureaucratic meeting).

Four-year-old laptop with busted screen (to drive the projector in the lecture hall).

New laptop (to consult my notes while lecturing).

Livescribe Pulsepen (to make backup copy of lecture audio in case Webcast system punks out).

I must say that I am very tempted to take all of them. They only weigh twelve pounds all together...
