An anonymous reader writes "Ars reports that Microsoft has announced pricing plans for Office 2013 that include a subscription-based model for home users. There will be a $100/year Home version that can be shared by up to 5 users and a $150/year Small Business version. 'Subscription software of one form or another has proven popular in the enterprise (whether it be cloud services, like Office 365, or subscriptions to desktop software, such as Microsoft's Software Assurance scheme). But so far it's a rarity in the consumer space. Anti-virus software has tried to bully and cajole users into getting aboard the subscription train, but the large number of users with out-of-date anti-viral protection suggests users are resisting. ... As another incentive to subscribe, and one that might leave a bad taste in the mouth, the company says that subscribers will be given unspecified "updates" to add new features and capabilities over the life of their subscription. Perpetual licensees will only get bug fixes and security updates.'"
