Microsoft is sending out a subtle reminder this week that, despite all of the fanfare surrounding its newly announced service, Apple isn't the only game in the cloud. Redmond has unveiled updates to SkyDrive, including speed boosts, a revamped UI, and improvements to photo viewing. The latest version of the almost four-year-old service has cut wait time on actions like clicking folders, from six to nine seconds down to 100 to 300 milliseconds. The updated software also features H.264 video playback, a navigation system more akin to desktop browsing, and a single view for files, docs, and photos. Let Microsoft hold your hand through a video tour of its cloud below.
