Between them, the five biggest tech companies have spent an average of only $3.4 billion a year on sub-$1 billion acquisitions over the past five years — a drop in the ocean compared with their massive financial reserves, and the more than $130 billion of venture capital that was invested in the US last year.

过去五年，这五家最大的科技公司平均每年在10亿美元以下的收购上总共只花了34亿美元——与它们庞大的财务储备以及去年在美国投入的1300多亿美元风险投资相比，这只是沧海一粟。
