Given how Sony is laggard in many areas, I can't help but think "four screen strategy" is two screens too many.
To me, Sony's PC business is basically a lost cause. Heck, most Sony employees use computers made by other manufacturers. Perhaps Sony is thinking of website as a way to bring "four screen" for PC, but why bother?
As for tablets, return of investment seems too limited given intense competitions.
That leaves phones and television. Sony is very much a laggard in...
