Apple, Microsoft, Google and the Open source world are the four competitors in this big electric game. All competing to be better than the others. Not so much the open source world but definetly Apple, the old shiny one, Microsoft, the middle age dusty dying one and Google the young, big and growing fast one.
This post is made mainly to point out that google is growing fast and Microsoft is being over-run. You could put it into a sort of dinasour analogy where Microsft is the big Braceasourus, Apple is the smaller herbivore(the one with the horns, I forgt what it's called) and Google is the Velociraptor family with the rest of the small selection of dinasours being the open source world.
Sorry about yet another short post but that's all I wanted to point out.
