I think we are quickly approaching a point of patent detente. Google needs to get a few more patents and indemnify Android OEMs and maybe lob a few lawsuits at Bing etc. and MS will quickly cross license. Same against Apple.
And while a few more entrepreneurs getting ground into hamburger by lawyers isn't that big of a concern in the larger scheme of things; it does mean that innovation in the tech sector is tamed and that we lose out on great products that never get a chance to compete in the marketplace.
The patent trolls don't understand detente. They don't understand MAD. They're the real threat, not Apple/Microsoft/Motorola/HTC/whoever.
