It's not that they don't have the manpower or resources, obviously they do. The point is that doing a whole OS like Maemo is outside Nokia's scope. Which only really needs to be done once then maintained in the upstream. It is an investment, but not whole-OS level and will pay out over time. No they didn't. They bought a company developing a proprietary OS that used a heavily augmented Linux kernel and open sourced it. They then reinvented the wheel and threw away the rest of the open source community. You are very, very anti-Linux and have yet to see a real basis for it. Well, that shouldn't be too hard, so long as the code doesn't do stupid CPU specific stuff and the compiler works well. Integration as a whole is done on a higher level and optimization is device specific. Because now only Nokia is developing Symbian, and must do even more than they did with Maemo. Nonsense. That cleaves your branding in half and gives the mobile space securely to Microsoft, since Intel won't be relevant in smartphones for a while.
