Microsoft is introducing a new licensing model for its Office suite--a $100 pay-as-you-go yearly subscription. Assuming you need/want Microsoft Office, why would you get the yearly subscription version versus the regular one-time software install? Let's take a look.
With Office 365, the Office subscription or cloud-based offering, you have to pay for each year of usage. That $100/year price gets you access not just to the core Office 2013 programs available in the download/disc-based version, though (Word, Excel, PowerPoint, and OneNote), but Publisher and Access as well. It also gives you 20GB of additional storage on SkyDrive, 60 minutes of Skype talk time and the ability to use Office on up to five PCs or Macs. So compared to the single-user $120 Home & Office Version and Office Professional version ($399.99) of Office 2013, this subscription could be a better deal if you need Access or Publisher and/or have multiple computers you want to run Office on.
There's a free one-month trial available here, in case you're not sure you want or need Microsoft Office 2013 (in the cloud or as a traditional desktop software suite).
One of the biggest changes to Office is it's now <a href="http://mobileoffice.about.com/b/2012/07/17/microsoft-office-2013-touch-friendly-and-cloud-optimized.htm">more touch-friendly (for Windows 8) and cloud-optimized</a>. A great new feature is syncing where you left off on one device and continuing on another.
