Another 'fun' fact. Sony is the only big company that is going to support Sailfish OS on their smartphones later this year.
They are not afraid to try new stuff.
Any idea what those ballpark figures look like today?
The E ink product you linked is a dev kit targeting a niche market, not a general CE product manufactured in the millions and benefiting from economies of scale...I'm simply not seeing the relevance of the comparison.
Visionect's 9.7" e-ink sign, which is their version of a digital picture frame, costs $400.[1] That's a product, not a development kit. A comparable LCD digital picture frame from WalMart costs $70. Color, too.
A friend's wife works at the United Nations, and a couple years ago I got invited to have a drink at their bar, I was really looking forward to seeing the e-ink wall display (made of tiles of smaller screens - not an entire surface) but unfortunately it was broken so I never got to see what it was like in person :( https://www.youtube.com/watch?v=pnb4tFK4I90
eInk still costs far too much per unit area. You can buy wall sign sized eInk displays, but they'll cost much more than an LCD TV panel of the same size. 32" diagonal display, $3,599.[1] Compare 32 inch color LCD TVs for $200 at WalMart. Despite talk of cheap "electronic paper" displays, the eInk people never delivered on cost.
