because tablets are going to get hardware updates the desktop market will go? what planet are you on? tablets won't replace PCs, netbooks maybe but not desktops or laptops. Google gets about 90something% of its revenue from advertising, not software like MS or hardware and software like Nokia. Most tablets run android but so what? none are huge sellers by any means. Android is popular because it floods the market and then enough people buy it from its presence, ditto Apple - its everywhere, part of Nokia's problem is lack of advertising. lot of weight behind it now
