ONYX Boox Palma e-ink w/ Plus42...

[Steve Simpkin]

I use a Kindle Fire 7 tablet as a 7" Android tablet for testing calculator emulators/simulators on that platform. It is normally $60 but goes on sale for $40-$50 several times a year. It was the least expensive option I found for an Android tablet. It did not come with the Google Play Store but that was easy to install. It is not super fast and only has an 8-10 hour battery life but it was cheap and works reasonably well. It runs an Amazon fork of Android 11.
