I got one earlier this week. It is a good value, albeit flawed device IMO. A much better experience for me than with Nxtpaper 3.
Its strength is the updated display which (counter-intuitively) with the 'e-paper' and 'eye comfort' modes disabled is fairly comfortable for users sensitive to flicker (no temporal dithering or PWM now). The anti-glare screen surface is also much improved.
However, as an all-round tablet it feels sluggish compared to an iPad and the speakers are very poor. Understandable at the price, but I would have been happy to pay more. That said, I'm going to keep it.
