What's AAPL's dividend yield?
Ohh wait, 0%
What is MSFT's? 2.0%.
You do realize that in 2004 MSFT dividended out 32 BILLION in cash to shareholders in one swipe and has, since then, dividended out ~4bn/yr?
You also realize that MSFT's stock price reflects present and future dividend yield while AAPL's price reflects merely expectations of reinvestment of cash?
You also realize that GOOG is a growth stock whereby earnings are highly volitile while MSFT is a value/dividend stock with sedate earnings? This is why MSFT only reached a 52wk low of 20% less than current price while AAPL was 50% below.
MSFT is also 5% more profitable than AAPL, largely because AAPL is expending more for R&D.
Stock price is meaningless, as is market cap.
Berkshire Hathaway pays no dividends.
