I'm sorry, but that's pretty much the most off base analysis I have ever heard. 1st Apple is what it is today precisely because it is not like Microsoft. 2nd Microsoft bares no resemblance to IBM. IBM is a enterprise focused company with it's hands in very few pots, but does extraordinarily well in the niche they are in. Microsoft has it's hands in everything and for the most part is playing catch up to more nimble tech companies who aren't allowing themselves to be stifled by legacy software and products.
As far as the security thing, that's just common sense. If you allow for automatic updates without user approval you open the flood gates to viruses and exploitations of other varieties. Just look at the crap that is going on with Android handsets. Something like 75%+ of all exploits on handhelds are happening on Android phones. Apple is basically 0%. Think about that next time you complain about your password.
