> Sony is almost exactly 1/10th the size of Apple (in terms of Market Cap).

Sony is also 130% the size of Apple in terms of revenue, 180% the size of Apple in terms of assets and 340% the size of Apple in terms of employees headcount.

> Sonly also doesn't fab their own processors for mobile devices like Apple now does.

Apple does not fab their own processors (for mobile devices or otherwise), and — up to the A4 anyway — don't have that much input into them (the A4 is almost of-the-shelf, we'll have to see for the A5 but so far there's been no great works there)
