But I think Google is much more prone to jump in to a market with force, they just seem to execute "better" (I leave that open to interpretation).
FB comes out and MS buys in whereas Google makes their own social network. Apple makes the iPhone and Google makes Android. Only much later (as the ship has already left port) does Microsoft come in with Windows Phone (I'm only considering 7 & 8). Somewhat related, I feel like MS and Dell were on target with the Axim from a product idea standpoint but Apple really capitalized on combining the functionality of a phone and forward thinking hardware and software design with iOS devices.
