I hadn't heard of the Pinenote before looking at your comment, so I looked at the site and saw some things that made it seem unfit for purpose as an ereader. I made my comment because I was interested in hearing your impressions if you were using it as a daily driver.

Personally I view stuff like this as a nice-to-have, not a must-have. If it means I can't have an interface where I can buy books and then download them to my ereader, or I can't have an iphone app where I can read books and have my progress synced between my ereader and my phone, or it's unstable, or the battery life isn't good, then I would rather go with the Kobo. I understand that different people have different priorities, but those are mine. Stuff like this is why I'm interested in hearing more detailed information about what exactly the tradeoffs are for going with something like the Pinenote.

I think you can still sideload KOReader on them, but that's a shame that they're making it harder to replace the stock OS entirely. I hadn't heard about that prior to now so thanks for bringing that up. I only have a Sage I bought a few years ago.
