Can't be cheap being a crowdfunded product, but not expensive either. The biggest turn-away I can see is the small screen. Most e-ink readers nowadays start at 6". A 4.x" screen will lose a considerable chunk of potential backers.

Yea, the screen makes it an instant turn off for me. Small and low res. Modern e-Readers like the kindle, kobo, etc. have screens basically as sharp as printed paper at a similar size as a book.
And with software like calibre, I don’t really see a reason to switch away from my kindle…

I switched to kobo only because kindle - I don't want to be an amazon billboard. I'm 100% calibre too, tho kobo do sell some drm-free ebooks.

My PW 3g was the absolute best ereader ever. Snappy page turns, perfect soft lighting, infinite batteries... funny unlimited worldwide wikipedia. Fuck amazon.

Thats the biggest issue for me.

I would carry around something with the thickness of a textbook and a 7+" screen, but under 6" is a nonstarter for me. I'd end up with text so large I'd be reading one sentence at a time.
