I’m very interested in the 7” device size, and Nielsen has some sober observations about it. Neither ordinary web sites, nor web sites designed for the 10” tablet or the smart phone, are easy to use on the 7” tablet. If enough people buy these things, and if, as a result, enough web sites are designed specifically for them, then they can be great online successes. Read Nielsen to see why.
Nielsen skewers magazine reading and book reading on the kindle as well, and his reasons make good reading.
