(Also the features Mastodon people will tell me about are usually not the ones in the mainstream reviews)
@Canageek I have a Kobo Clara HD, which isn't a new model, and I like it, although it has developed a faint horizontal line that doesn't refresh properly, but I can work around it.
What I like: small (6-inch), so I can stuff it into my pocket and take it out to read while waiting (for family or while queueing) or on public transport. Also syncs with Pocket and my local library (Overdrive), so I never run out of things to read. Much lighter than a tablet and battery charge lasts longer.
