I'm not sure though if Sipix is a reflective screen. Is it?
Yeah SiPix is very similar to E-Ink. They're both EPDs (electrophoretic displays), and operate on the same general principles. SiPix has some advantages in thinness and durability, though it is visually a little inferior to E-Ink (lower white reflectance in particular, making the screen a little more gray. The numbers I see are ~30% for SiPix, ~40% for E-Ink)
Here's a video that shows a reader that uses a SiPix Microcup EPD screen:
After 2 minutes you'll see the display in action, and you'll notice it's slow, just like most E-Ink devices. Demonstrators love to re-tap and re-swipe to try to conceal the lack of responsiveness in a device. To be fair though, that's likely the processor and software. Personally I think their huge demonstration "reading" text is hilarious.
