2 questions/points to ponder:
1. How much cash does AAPL have as of Apriil 22, 2011
2. Doesn't the cash after say $30 billion basically become just investment vehicles? You can do all the pre-purchasing of supplies + R&D with WELL under $30 billion for a company like Apple. Essentially companies like MSFT/AAPL/Google with HUGE cash reserves become like banks.
