Soap Opera of Google and Apple- Are we missing Microsoft as yet?

Strange how we now read news of Google and Apple having a face off with each other with little mention of our good ole timer Microsoft. Google releases their Nexus One cellphone against the popular iPhone model, quite a bold step into the highly marked territories of Apple. In turn, Apple has just acquired Quattro Wireless, a mobile advertising company. The stakes at this turf war seem serious. And much like a good Hollywood script, the cast of characters are set. Apple and Google, who bonded in the past over their mutual enemy, Microsoft, are now finding themselves in line of each other's fire. The question is...why is Microsoft silent in all this? Is it because its had its time of day? Is it because Microsoft without Bill Gates is like a sizzler without the sizzle? Or is Microsoft learning the benefits of spectator sport?
