Microsoft just announced that Outlook.com, its well-received update to Hotmail, now has 10 million users. The redesigned Outlook.com user interface is now also starting to appear in other Microsoft products and today, SkyDrive.com, Microsoft’s online storage service, is getting a major design overhaul. The new design features the same Metro/Windows 8 look as Outlook.com, with large fonts, tiles and other new design elements.
