<p>Computerworld - Two weeks ago, Microsoft backpedaled from a sweeping change on how it licensed retail copies of Office 2013, deciding that it would, after all, let customers move the software from one machine to another.</p><p>That reversal mooted the original end-user licensing agreement (EULA), which had permanently tied "perpetual" licenses -- those paid for once, with rights to use them as long as desired -- to the first PC they were installed on.</p><p>And it again made for fairly straight-forward calculations when trying to decide the better deal between buy-once-run-forever copies of Office, and the rent-not-own deals that Microsoft wants consumers to adopt.</p><p>Office 365 Home Premium, which costs $100 per year -- or $10 per month -- includes the right to install a top-end edition of Office 2013 or the business-esque edition of Office for Mac 2011, on up to five Windows PC or Macs in a household.</p><p><a href="http://www.computerworld.com/s/article/9237780/Microsoft_Office_2013_vs._Office_365_price_calculator">Keep reading...</a></p><p>Read also:</p><p><a href="http://www.computerworlduk.com/news/applications/3436441/microsoft-discontinues-office-2010-sales-some-retailers-jack-up-prices/">Microsoft discontinues Office 2010 sales, some retailers jack up prices</a> (ComputerworldUK)</p><p>Explore: <a href="http://news.google.com/news/more?ncl=d01IWCk0o1PdcBMdoChDgFVcQWnXM&ned=us">2 additional articles.</a></p>
