'We can compare LibreOffice to OpenOffice.org to Office till the cows come home,' says Proffitt. 'But what happens when Google Docs gets truly robust enough for business and high-end document production? Or Prezi gets enough mindshare to start an upwards trajectory of user numbers?' It should be the case that increasing reliance on cloud software will make it easier for businesses to choose Linux, but for that to happen, Linux communities need to stop fighting the old fights, says Proffitt."
