jaark, do you want to compare Nokia and Google? True, Google don't have a large presence on the smart phone market, but they are just starting...
Also, what is this stuff about the "core Windows kernel"? I think that comparing hardware and software companies is flawed logic... Instead of Windows, you should say MacOS.
Do you all think that Nokia would be where it is on the smartphone market if it had a single phone model for each Symbian version?
