The video embedded below shows the Hisense Q5, a new tablet that's reportedly coming out in China this week. It has a reflective LCD display, similar to e-ink (in that it looks and feels much more paper-like than a typical screen) but with much faster refresh rate than you'd get from a Kindle. But it also shortcomings of its own, such as a lack of persistence and less efficient energy use.
It clearly handles animated UI elements and videos with ease, and the question is whether it looks better in real life, in the gloom of an unlit room or the glare of midday sun, than the similar but doomed Pixel Qi.
Though it's otherwise an unremarkable $350 Android tablet, it does have a HDMI port, meaning you could use it as a 10.5" display. For comparison, a standalone 13.3" e-Ink display has a four-figure price tag [Amazon].
