Good points:
1. the n900 is just another high end, early adopter, geek toy, and not a full out change in OS strategy and direction toward Linux
2. Apple has some of the tightest hardware and software integration ever seen in mass production consumer electronics of this class
3. hardware, Nokia's special sauce, has become such a commodity now, that it is a race to the bottom on cost
4. for the foreseeable future, true value creation is in software and the sad truth is, Nokia simply does not have the software culture required to compete on the same level as players like Apple and Google
5. Nokia is a hardware company that buys their software and they will be hard pressed to compete against Apple with this strategy.
