Sony’s launch of its first tablet devices is bound to excite unflattering comparisons with revolutionary Sony products of the past – particularly because it falls in the same week as the death of Norio Ohga, the Japanese company’s former chairman and chief executive.

As every retrospective of Ohga’s extraordinary life has pointed out, he was the Sony executive who helped establish and drive the compact disc. By contrast, Sony’s “S1″ and “S2″ (their temporary names, thank goodness), already seem doomed to be mere “iPad rivals”.
