Good points Sinocelt and I know, I agree with you and with them completely. But this product here is basically an eReader despite the prefix "not" in its name, plus e-ink panels, while being absolutely amazing for reading and displaying a lot of static content, are really way too slow for regular/usual tablet-like usage, no? But as an eReader or especially as an external screen this product looks pretty damn fine despite now really obsolete Android version. I mean, how really important is up-to-date OS if you plan to use it as an external screen plugged in your PC to enjoy reading a lot of text on it, hm?
Newer Android versions have benefited from security improvements.
Some apps simply refuse to work with Android versions older than X. That was a problem with my old phone: some of the apps I had updated themselves... then told me they couldn't work with the Android version installed on my phone.
Dasung presents a versatile e-ink tablet in the Not-eReader 133, which can also be used as an external monitor for a computer thanks to the HDMI input. With an economical and high-contrast E Ink Carta 1250 display, the tablet promises a particularly long battery life.
