6. Notams pertaining to your route into the aircraft? Forget it.
I've had notams relayed to me by controllers on more than one occasion. Such as "did you know that after you took off a piece of airspace at such-and-such has been notamed closed because of an unexploded bomb?".
I think I'd rather have that then yet another gadget to learn how to use, remember to switch on, and take time away from looking out the window.
