Except of course that MS has 9 billion outstanding shares verse Sony's 1 billion, which of course is why Sony had a much higher per share value until recently.
Stock price is a reasonably bad indicator as opposed to market cap because some companies like Microsoft are notorious for splitting their stock when the value reaches a certain point (back in the day they reached around $100 a couple times and split to $50), it helps make stock purchases more feasible for regular folks.
Anyhow a lot of the Sony's in dire straits is speculation at this point, in other words you need to wait until a week after Sony releases it's quarter reports to see how the news has really impacted the stock.
