Microsoft's SkyDrive cloud service has languished for years, but that will soon change with the arrival of Office 2013 and Windows 8. SkyDrive, in fact, is being positioned to play a key role in Office users' day-to-day computing lives. Office 2013 saves your documents to SkyDrive by default, enabling you to access files across multiple devices, including a smartphone and tablet. When you sign into Office, your personalized settings and recently used files are already there for you.
The new Office is available as a cloud-based subscription service too. Office 365, currently sold to businesses, will be available to home users as well. In addition to receiving future Office upgrades automatically, subscribers will get additional SkyDrive storage, multiple installs for several users, and added perks such as international calls via Skype. You'll also be able to stream Office apps to an Internet-connected Windows PC. Microsoft hasn't announcing pricing yet, but plans to do so this fall.
