The Boox Nova 3 Color combines great hardware (for an eReader) with backlight-free color technology. Unfortunately, it comes just as two other reflective color panels near release: TCL's NxtPaper transflective LCD panel and E Ink's potentially game-changing Gallery 4100 technology. Both panels may make their way into Onyx products.
In my opinion, despite its bugs, the Boox 3 Color offers something unique to eReader enthusiasts. It's a high-end 7.8-inch color eReader. If you need color right now, it's worth its $420 price tag. For those who can wait, we haven't yet seen what E Ink's Gallery 4100 or TCL's NxtPaper can do. I'd advise waiting until the new technologies come out before buying.
