Microsoft's new Office 2013 and Office 365 launched today for non-business customers.

The main functional improvements in Office 2013 come through Microsoft's new Office 365 subscription service which is a definite change.

The $100-a-year subscription is one of the biggest issues with the new Office and a potential inconvenience to Microsoft customers, according to CNET. Users will be able to install a version on up to five PCs, Macs or mobile devices by using the subscription service.

Subscribers also get more SkyDrive storage space with 20GB and 60 minutes each month of free Skype phone calls to 40 countries, according to PC World.

Customers will also have the ability to do a one-time standalone purchase of Office 2013 for $139.99 to $400.

What 365 essentially does is turn Office into an Internet-connected app, allowing you to save documents in cloud, collaborate with others, receive regular software updates, and use a remote version of Office from any computer if people are in need.

The new Office suite by Microsoft come in a variety of packages developed for the particular need for the consumer.
