They've been doing this for YEARS before Amazon.
It's fine if it fits your need, but will be far from a good alternative in most regions.
For this feature alone, I'd never go back to Kindle. Sure, I might be able to replicate it with jailbreaking + KOReader. But the Kobo worked this way out of the box.
Because Amazon were increasingly locking-down their systems - and also because they are all-round shits - I decided to abandon the ecosystem having been a customer since the days they only sold books.
I have owned two Paperwhites, two Oasis devices, and a Kindle Scribe. I sold all of them last year and bought a Kobo Libra Colour.
I get WAY more joy from reading on the Kobo. I love buying books from the Kobo store (yes I know they also have DRM) - and I'm buying and reading WAY more on the Kobo than I was at the end of my time with Amazon.
Every time I buy yet another book on the Kobo Store I feel the thrill of sticking it to the horrible, anti-user shits at Amazon.
I have a Kobo Clara BW. It's still a great machine, but the Kindle is definitely superior for feel and visuals, but I use the Kobo 95% of the time. They are way more open with the software and I have mine in "sideload" mode (an official setting), which really just means that it doesn't make me log into anything and it doesn't even attempt to connect to the internet. Also, I can purchase a DRM free ebook on the train, plug a USB cable into my phone and my Kobo, and then load it on like that. Now I own my digital book, have supported the author with a larger margin, and get to read it on my more private machine.
Definitely not a no-brainer for everyone, but I'm happy with my Kobo.
Kobo feels like something I actually own. More so than Kindle or even my iDevices. That's a little unusual these days from a mainstream product and that will make its users enthusiastic.
Asking people to verify that they are honest will never help you. Dishonest people will of course lie to you and say they are honest. While honest people will be insulted by your question and not want to engage with you.
What you can do is verify. Try a Kobo, try a Kindle. Make up your own mind.
It would be great too to bring that information back to HN and share it with us.
What I found disappointing was when I had to swap out the screen on the Kobo and found that it was glued and that the battery was soldered. I managed to do fix it, but I don't like things that are unnecessarily hard to fix.
