Ipad not an e-reader
Yuck, so now pilots have to be staring an LCDs? If you're going to replace paper, replace it with something at least as good.
And are they going to have to wait while the Ipad needs charging after every trip? What happens when it runs out of battery?
E-readers (which the Ipad is *not*) with e-ink technology would be the candidate to look at. Even there though, replacing paper in these situations is dubious. I don't think replacing paper makes sense until we get a technological equivalent to paper - e.g., the "electronic paper" that is being developed.
The sad thing is that even when we have electronic paper, that looks just like paper, can be rolled up, doesn't need power to update, can display colour and video - Apple will release an expensive tablet based on outdated LCD technology with an Apple logo, and still win all the hype, because "Ooh I can't play games on the electronic paper model and it isn't as reflective!"
"I guess the Kindle vs. iPad argument depends on whether or not colour and/or graphics are involved."
There should be no more a Kindle vs. Ipad argument than say, Kindle vs. Netbook, or Kindle vs. any other non-e-reader device.
The actual argument should be between Kindle vs. Sony E-reader; or E-reader vs. Paper.
F111F: If it's about the maps, Nokia have been providing offline mapping software (i.e., no network connection needed) to ordinary people since before we even started getting rumours about Apple's vaporware tablet. I don't see why it's news that Apple can now do it years later.
