My Kindle is always in airplane mode as well =)
And I love e-ink feeling (besides an LCD screen) that is a good compromise between an electronic device and a decent screen.
Wow, didn't know about that 'manga reader'. I was looking for a bigger device (9 inches perhaps), but they are crazily expensive.
The 6 inches from Kindles are good enough for only text, but horrible for any magazine or even diagrams, so I'm intrigued...
I love the portability! I could go for months on a road trip with no internet and still have something to read!
The only thing that my Kindle can't beat is the feel of real paper. Turns out there is actually a "manga reader" built by progress technologies that uses real paper in the design. It's super expensive from what I understand, but it looks like an actual book and has two screens in a book style view!
eReaders are getting crazy :3.
