We’ve been promised electronic books since before I was born, but the last year or so has finally seen a number of examples of viable technologies appear. A lot of big names are in the running, seeing a great market opportunity waiting to be exploited, and the latest team to enter the race are Amazon – Engadget managed to snatch an FCC document (now removed) that lays out the spec with pictures. It looks pretty ugly, to be honest, but if it’ll do the job it’s sure to sell – to the early adopters, at least. No word on price or launch date as yet.
