For the main purpose that they are used for, displays that don't need to be updated frequently, like e-reader or "smart" price tag display.
However updating the display is more costly in terms of power than lcd.
We can also factor in that most e-reader also include backlight.
As a caveat, I appreciate e-ink technology, and the innovation that it brought us. I would also love to get my hand on one of those color e-ink android tablet. But I am not hoping to have a huge difference in battery usage from it, e-reader are very specialized device and can afford optimization that more versatile device cannot.
as if being 1.6 heavier does not matter? Or 1/3rd of price?
I can hold kobo libra 2 with one hand, the battery lasts long, PPI is high, what to not like?
The Y700 came with a rubber case which makes it significantly easier to hold than the plastic Kobo. The metal body and minimal bezels also look much more premium.
It's also _extremely_ better at everything, including for reading books, so the higher weight and (2x, not 3x) cost are well worth it.
The Kobo battery doesn't even last that long with the backlight and wifi on, and at least mine wipes its storage and OS when the battery runs down completely. The screen and UI are also the worst thing imaginable. Using eink devices is basically equivalent to torture.
You come across as biased and angry, which makes your statements unconvincing. In what universe 375g device is easier to hold (with 1 hand) than 215g I have no idea, esp. keeping in mind that kobo has buttons for easy scrolling with one hand.
You also miss the point, that limited functionality of readers is feature not bug. It massively reduces impulse to start browsing youtube etc.
All together, price, weight, battery time and limited functionality is what makes the whole proposition attractive. I personaly do not need yet another androd tab even for free.
