One of the cool perks of Surface RT is that it comes with a copy of Microsoft Office Home & Student 2013, which includes tablet-optimized versions of Word, Excel, PowerPoint and OneNote. Surface Pro? Sorry, you'll have to bring your own productivity suite. That's not a problem, however, for enterprises with volume licenses for more advanced versions of Office (such as Professional Plus), or those already running competing suites such as Google Apps. Besides, many business users probably wouldn't want Office Home & Student 2013 RT, which can't run macros, add-ins and other custom programs from users or third parties.
