I bought the InkPalm a while back, and the Palma recently. (Note: I have a "thing" when it comes to e-Ink devices and so tend to just pull the trigger on new interesting ones when they come out.)

They're superficially similar, but the InkPalm feels like a very limited device by comparison. No Play Store, slower refresh, much older Android build, and a mostly-Chinese localized UI with partial English translation.

If you really just need a basic e-reader that can handle MOBI and ePub files and are willing to put up with a somewhat frustrating experience, the InkPalm is fine. OTOH, if you spend a lot of time reading long-form text but also want to occasionally run other apps -- Termux in particular is a pretty great tool to have on a small e-Ink device when paired with a small BT keyboard -- the Palma is meaningfully better.
