Which is, I think, the arch point of Gruber's quip. If Microsoft had bought Apple in 2006, does anyone seriously think Microsoft today would have a dominant position in phones, music players, music distribution, and tablets? Would it have a world-class retail chain?
Moving forward to 2011, people point out that B$8.5 could buy a lot of startups. Assuming that they could identify it, Microsoft probably could buy the next Apple or Google. Heck, they could probably buy it just by trying to buy everything. But does anybody seriously think that if Microsoft does buy the next big disruptive company, it would still be the next big disruptive company?
