[Dr. Drib]

Sorry, no. I don't like the 'murkiness' of my Kobo Libra Color's screen.

Fortunately, I have a host of other ebook readers, so I can occasionally - and nostalgically - take it out of the drawer and remember how much I paid for it, in addition to having purchased the official Kobo cover and the official clear back.

To the OP's question in his last paragraph: [B]Do I find the "color screen an enhancement or just a marketing novelty?", I would have to say neither of your two options are satisfactory for me. I DO think it (and Amazon's ereader) represent the beginning of color and, for some individuals, they may be satisfied at this stage of the technology. I thought it would be for me, but unfortunately I was wrong.
