I totally have my eye on picking up the Boox color ereader. I currently have the Kobo Elipse 2E device, and while I like it, having a color option would be great since it's only uses black and shades of gray. I think the cost was a few hundred dollars, and the Boox is what, $500? However, it seems to be worth it for the dash of color and the other upgrades. I hope you enjoy it! :)
Yeah, the Boox is significantly more pricey... I do think that there are other brands starting to come out with colour versions with the same Kaleido 3 colour technology. For me, I really needed something that had proper Android support so that I could use it for music as well as a slow refresh tablet.
