Along similar lines, I speculate that Microsoft snapped up Nokia because they threatened starting an Android line of phones.
I think there's a significant business lesson in here somewhere... Something along the lines off "partner with a giant, then become dangerous to it"
Funnily enough, MS also gets a nice patent bonus along with its purchase as Google did with Motorola. However, I think Nokia's patent portfolio is much, much more powerful than Motorola's. This is for three reasons, two publicly evident and one anecdotal:
1) Apple admitted defeat in its patent fight with Nokia, something it hasn't done with anybody else;
2) Nokia has multiple patent lawsuits ongoing, and none of them involve standards essential patents, the one thing most likely to invoke the ire of the antitrust gods;
3) A previous boss of mine knew the head of Nokia R&D in America, and he regaled me with stories of smartphone apps they had working in their labs way back in 2006 that made me go "how the hell do they do that?" Unfortunately, any two-bit app developer can do those things today on any modern smartphone platform using publicly documented API. But I am still curious about what goodies they have hidden away in their labs today.
