550,000 x $15 a handset = $8.25m a day for Microsoft in royalties?

$8.25m x 365days = $3,011,250,000 a year in royalties?

Is MS making $3B a year off of Android?

Well, $5 from HTC, probably none (?) from Motorola.

No doubt they're making a fair amount of money though.

Motorola is currently being sued by Microsoft.

What are the royalties for?

Patent licensing.

This is 16.5 mil a month or nearly 50 mil a quarter.

The staggering thing is that they are activating about as much in a quarter now as they did in all of 2010. I honestly thought it would plateau by now, but it hasn't. It's truly hard to appreciate how big the Android tidal wave really is.

Actually, the top 3 at Google insisted on calling each other by their first names in the IPO papers, to the chagrin of the SEC.

tl;dr ... haha not really. Google is on a roll. I both fear and love it.
