Four tech firms - Apple (AAPL), Microsoft (MSFT), Cisco (CSCO) and Google (GOOG) - sit on the largest cash piles in the S&P 500, excluding financials. It's a combined $147B, enough to bail out Greece. Possible uses for all that dough: Share buybacks, acquisitions such as SAP-Sybase and HP-Palm. Not likely: Dividend payouts.
