Time for the Sony Reader, which can be pre-ordered from Waterstones from this week. Much as I'm keen to get my hands on one, it's hard to get too excited about a thing that's only like the drabbest paperback book but lighter. I want sound, colour, links, movies to intermingle with the text, and the means to comment on what I read. I gather full colour e-ink is on its way. The breakthrough is that these devices may convince readers that there's no reason why literature should be wedded to paper, and will open the way to more exciting interminglings to come.
