1) Kindle will not work with epub, or many other formats. Libraries typically use epub format.
If it's non-DRM epub, it can be converted to mobi (non-DRM).
2) B&N nook color will be a complete android platform soon. Read any format. Or just use your phone and/or computer to read any ebook format.
Again, if the content I want is available via Amazon or via a semi-easy process to convert or upload, format is not an issue. Design and use of my preferred reading device is key -- the Kindle.
3) Ten days without a recharge is, typically, not needed.
Unless you don't have a charger with you. More important when you read on a device that doesn't have e-ink. iPad ain't going to last long enough, even on a short trip.
4) No color.
The books I read are still in black text on white background.
5) The "LED eye strain" claims are a hoax. I read an LED all day without eye strain. I'm 52 and I have never had great vision.
I assume you mean LCD. I concur when you talk about regular lit environs such as a home or office. I mean we use LCD's day-in and day-out via our computers. Outside though in direct sun, nothing beats e-ink.
6) Kindle does not work well in dim light.
Get the new cover wit integrated light. Runs off the Kindle's battery and is one of the best designed solutions I've used so far.
7) Kindle is a unitasker. Why carry around a kindle and a notebook, when a notebook will do everything you need? Why have a kindle and an android tablet, or a kindle and an iPad?
Sometimes, a purpose-built device overcomes the unitasker shadow. My phone, iPad and laptop provide 20-80% of the experience I look for when reading a book. The K1 provided 80-90% of that experience, and the K3 is 99% of the way there. Heck, even Alton Brown has unitaskers in his kitchen when they provide a much better function than a general use tool.
8) No touch screen.
For a book, it's not something I need. On the K3, the only time I wish I had touch capabilty is when navigating a page to look up a word.
