There was a programme about these devices on Radio Four last night. The general advice was to wait as better and cheaper are coming to the market soon. There was considerable discussion, as might be anticipated, about traditional publishers being as obstructive as possible but the feeling was that these problems would be overcome along with those associated with reading from screens and possible "eye- strain", headaches etc that have apparently been experienced by many users. The summary seemed to be that this technology is improving, that prices will dip below £100 in a year or so and that they may well be the next "must have".
