Full disclosure - I've already ordered one because I am excited to try and develop out in the sunshine, and laptop screen isn't cutting it. This is USB powered, and I'm hoping it will be good enough for text editor. Anyone had experience with these or any other e-ink devices?

I was really excited about e-ink technology, but it seems that there is very little innovation in this space, and I can't help but think this will really help for reading articles etc. too.
