Wow, what a great headline…
I read an article at Laptop Mag regarding a prototype Android phone that uses an E Ink display. My inner critic decided to outwardly criticize, producing a rather lengthy blog comment. I reprinted the comment here on my own blog because… well, why not?
Laptop Mag’s hands-on demo:
Notwithstanding the super-light weight and super-long battery life that E Ink affords this device, the display is a showstopper. The talk about using an older processor is a red herring; a faster processor won’t fix fundamental characteristics of the display. The currently available generations of E Ink give you a trade-off between refresh speed and power consumption; crappy refresh rates mean long battery life, fast refreshes are draining.
The E Ink screen is great for displays that don’t require rapid refresh, but this prototype demonstrates how inappropriate it is as a smartphone’s primary display.
When you buy an Android phone with multi-touch, the implication is that you’ll be interacting using finger swipes and taps, and that your interactions produce feedback quickly enough to make the experience seem natural and effortless. What we think of as normal single- and multi-touch functions would lose much of their utility; pinch-to-zoom, for one, would be a noticeable series of zoom-in steps (instead of a fluid growing and shrinking effect), something you could achieve with a zoom-in button and a single finger.
I’m not trying to bad-mouth E Ink, here – this is just not a viable application until/unless E Ink rolls out a display that gives you imperceptible refresh without massively increasing power consumption, hopefully at a reasonable price.
It would be cool to have the option of swapping your phone’s display, either physically changing it for another one or flipping one over the other like a book cover. There are times when I wish my display was e-paper, but then I look at my Motorola F3 and all is forgotten.
