Billly Gates writes "It appears Microsoft is following Chrome's agile development model like Mozilla did. At a recent tech conference, Kurt DelBene, president of the Office division, said they have mechanisms in place to update Office on a quarterly basis. Of course to get these new wondrous features and bugfixes you have to have a subscription to Office 365. Are the customers who most prefer subscriptions (corporate) going to want new things in the enterprise every 90 days? It is frustrating to see so many of them still on IE 7, XP, and Office 2003, which hurts Windows and Office sales and holds back innovation. At the same time, the accountants notice significant savings by keeping I.T. costs down with decade/semi decade updates to their images, while I.T. only puts out fires in between. Will this bring change to that way of doing things, or will Microsoft's cloud offerings with outsourced Exchange and Sharepoint make up for it using cost savings and continually updated software in the enterprise?"
