An aside, when you're airline traveling with these e-reader things, do you have to yank them out and put 'em in a bin for scanning as you do with laptops and tablets? I assume so, just wasn't sure with something as relatively tiny as the Nook.
No actually. The TSA has decided that iPads and e-readers do not have to be taken out of your bag. I have found they open my bag more often now that I did prior to lugging the iPad around (25% of the time), but it hasn't been a huge issue.
They do ask that you not use the devices during takeoff and landing though, which is in my opinion the only downside of e-readers vs physical books.
