Yeah, I’ve had a couple Kobos. If you just want to put arbitrary documents on it to display, they work well.

I think that the problem is, though, that while eInk ebook readers are really good ebook readers, they’re a specialized device in a world with a lot of general-purpose portable devices that people are already carrying.

They have extremely long battery life compared to an LCD or OLED display, and they work fine in brightly-lit environments like outside on a sunny day. And even if you want to use them in the dark, they have a soft backlight that can use very little power. And they’re really light and thin.

But…I carry a smartphone. And a tablet. And a laptop. Maybe not everyone carries all three, but they probably have at least one of those. And so you gotta ask yourself whether you want a really good ebook reader that’s only really good at reading ebooks (and can run a web browser or similar slowly and poorly), or whether you can tolerate using a device that can read ebooks and can also do things like browse the Web and play videos.

I’d only really suggest that someone consider a dedicated ebook reader if they’re regularly carrying paper books around with them because they want to use those books outside or the like. I do that and I still don’t think I’d get another ebook reader. It just doesn’t buy me enough extra functionality.

I often want to use a non-ebook-reader device to refer to the Web or something to look up something related to a book that I’m reading, and if I’m doing that, I’m using a general-purpose device anyway.
