Topple MS? How so? MSFT hasn't been toppled, they have just failed to increase their dominance in other areas of contemporary computing.
Microsoft still makes $70+B per year in revenues. MSFT is no where near being toppled, except in mindshare, they made record revenues last year. MSFT, AAPL, FB and GOOG are the top in their own separate verticals, and none can make a dent in the other's vertical. Arguably FB and GOOG are competing for ad revenue dollars, but FB is the leader in social networking, and GOOG is the leader in search.
