Onyx Boox Prometheus 2 Android eReader – $422

Onyx has a number of cutting-edge gadgets like the Onyx Typewriter, Onyx Boox Monitor, and the Boox e-Note in the pipeline, but that doesn’t mean they’ve stopped releasing regular ereaders.

The Chinese ereader maker has just launched the Prometheus 2, a 9.7″ ereader, in Russia.

The Boox Prometheus 2 runs Android 4.0 on a  1 GHz Freescale i.MX6 CPU with 1GB RAM, Wifi, and Bluetooth (but no audio).

Its 9.7″ Carta E-ink screen integrates a capacitive touchscreen and frontlight, and has a screen resolution of 1200 x 825. In terms of storage, it has 16GB internal memory and a microSD card slot.

It measures 9.5mm thin, weighs 450 grams, and packs in a 3Ah battery.

Retail price is 23,990 rubles, or about $422 USD.

All in all that is an unimpressive ereader with a steep price tag. The OS is old, the screen resolution is low, and aside from the Carta E-ink screen there’s little to distinguish it from previous Onyx ereaders.

You’re better off waiting for the Boox e-Note, which is due out in September.  The e-Note has the new 10.3″ E-ink screen with a screen resolution of 1404 x 1872, or 227 ppi.  That is considerably sharper than the screen on the Prometheus 2, which is 150 ppi.

    Why they still use Android FOUR in TWO THOUSAND AND SEVENTEEN?!?!?

    It’s really astounding. They don’t use the advantages of the next three major versions of Android 🙁

    And why CPU is so anemic in 2017??!?!

    just compare it with yotaphone screen…

    Outdated hardware and very expensive, obviously the sales are very low.

    The world really doesn’t need new 150 dpi ereaders in 2017.
