Dude, all comps are pc's: pc= personal computer!
...but anywho, since when as novelity been a factor of user base. If this was so, then you just proved yourself wrong! This is the way your argument reads right now: Mac is novel, therefore there user base is expanding. This is countered by the fact that every other computer in the world is not a mac (a majority, you will agree) which thus means the other computer companies must be more novel! Do you see?
I disagree with your greenest on earth argument. They use lead. They use arsenic. They used unnecessary chemicals in the Iphone that no other company used (and was recently released in a news report if you had been paying attention, no offense meant). All cells do use "bad chemicals", but some worse than others, and the Iphone would be one that uses much worse chemicals. I do not believe that Apple is very ethical, as it is a company. The profit margin matters more than anything else, and that is why their products are assembled in other 3rd world countries at a huge profit, and why their products are grossly overpriced compared to their use.
With the speakers, my point is that these companies made deals with Apple to manufacture products that exclusively cater to the ipod, and do NOT accept any other products (they won't work with sansa, dell dj, zune... the list goes on). This is a form of monopolization, albeit more subtly.
So here (I give you that they do have their problems (Ipod to PC) but they to much more to keep those to a minim as posabule they aren't a huge company like microcrap.) you are saying that the reason Apple is good is because they are small, and the reason Microsoft is bad is because they are big? If this is the case, and Apple indeed surpasses Microsoft... then wouldn't the reverse occur? I also notice you haven't said anything about any other company... say Acer, Asus, HP... all the other competitors which are almost as big as Microsoft, or bigger.
... but no need to get mad at me for this, I just find it difficult to make such generalizations (although I do occasionally). I should in fact say that Mac is innovative at times and novel as well, but so are all the other companies too.

-dom out!
