I've been using the Voyage since it first came out (on my 3rd one -- 1st was stolen, 2nd stopped working during warranty period). I really, really like it but it seems to be getting a bit flakey (have to do a hard reset every month or so). I also recently had a scare as I left on a plane in Amsterdam on my way home to LA -- diligent work by KLM (and $80 to DHL) got it back to me. In the meantime I had to use an older (bought 2017) Paperwhite and I really really hated it. It got me thinking that I would be looking at a replacement (for when it happens) and so I am here.
I do also have a reMarkable -- which I find too large to use a general eReader (though I love for note taking). And I have tried my brother's Oasis which I also did not like (neither does he, that is why he let me try it
)
I do have a bunch of Amazon books, but the vast bulk are under $5 specials I got at one time or another -- most I had trouble reading once, so re-reading them is not an issue. I so I am not tied to the Kindle ecosystem.
It looks like the Kobo lines are pretty much the only alternative out there?
