Re: Apple
...how have Apple been able to keep on doing this on OSX (after Microsoft Windows decision with IE) and with iOS (Safari is the only browser preinstalled and there is NO other App store option).
Apple does not have a monopoly share of the market, and never has. They may have a monopoly on iPhones, but >80% of the smartphone market is Android. Before Android took off they were in third place behind RIM and Symbian.
