The phone sized one? I always look at them, but end up buying sats instead. They do look cool though.

I got the go, which is slightly bigger than a phone, but not a full-sized tablet.
I'm thinking the Palma 🤏
In my couple months of useing one, it seems like decent hardware so far. I haven't really had any major issues. I don't see why that one would be any worse. I just wanted a slightly bigger form factor personally.
Yeah I got a huge one now, a Kobo. The small form factor could be nice for traveling. Might be a cool bitchat device too.
For reference, this is the size of the go. Palmable, but not the size of a phone. 
How is boox in terms of keeping Android up to date?
I'm trying to migrate to GrapheneOS only for Android devices household wide, so that makes me hesitate to go to an Android ereader because I would have to give up that dream.
In that aspect, it's not too great. The current device I have is running Android 13, which is about two versions behind. And in terms of security patches, they don't typically push updates super fast if at all. They rely on getting patches through the play store and if you're going mostly graphene and that's obviously not acceptable for your household.
I'm using a Google Tablet with GrapheneOS.
Not bad. I keep my news feeds on there, don't do many books from it.
Dang that looks perfect 👀
