Comparing new WiFi model to new 3G model, out of airplane mode, the 3G drains about 2x to 3x faster than WiFi model.

We were still pretty pissed at the blatant false advertising (a hardcore book reader reads for only a half hour a day!?!), but moving forward, she keeps the device in airplane mode 95% of the time, only turning it off to download whatever new book she just bought. It increased to at least 2-3 weeks after that, instead of a single week.

You can keep the display of the kindle on for hours at a time with minimal drain
Of course, modern e-readers have a backlight. Though you can never fully turn it off, at least on my first-gen Paperwhite, which is unfortunate.
As I said, functionally, it is marvellous. But using it interactively is painful.
Once that's done you get a "My Articles" option in the hamburger menu, and that's your Pocket content.
I then go to a cafe next door and read them. They don't look like an ebook on a Kindle, more like a Kindle magazine. I adore that feature.
The Kobo integrates Pocket natively, so it works seamlessly. It's one of the reasons I bought a Kobo. Native Overdrive integration was a huge plus, too.
