43: Office 365 Home Premium
Microsoft Office is nothing new—but Office as a service is.
Office 365 Home Premium lets you subscribe to the productivity suite for $10 per month or $100 per year. While the stand-alone (not to mention pricey) Office 2013 software works only on a single machine, an Office 365 subscription gives you the right to install the full-blown Office Professional 2013 suite on up to five PCs and Macs, plus five more Android or Apple phones.
Plus, Office 365 includes synced settings and files, instant updates, Office on Demand, 20GB of additional SkyDrive space, and 60 monthly Skype world minutes.
Sure, you might not “own” Office 365 the way you do Office 2013 proper, but that's still one sweet deal.
