Well,
Maybe that's it Doc. Carry one EFB (iPod size) and a backup, either a phone sized backup or simply printing the few charts you know you'll need (destination and alternate).
If you're headed into Adelaide for example you can probably trust the EFB far enough to only print out the 23 ILS and 05 VOR. 99% of the time the EFB will get you all the rest of the plates like STARs etc but if you're having a bad day you can always ask to be vectored to the approach and specify that you require one of the two plates you are now limited to.
