"Just four months after its big coming out party at CES, U3 -- a platform for running applications from USB thumb drives -- has already been put on the chopping block by parent SanDisk. The company has decided to join Microsoft in creating a new standard. U3 was first introduced in 2005, backed by a host of supporting software and hardware vendors. Popular applications including AOL's Winamp, Cerulean Studios' Trillian, McAfee Antivirus and Skype among others were offered in U3 versions to spur its adoption."Without Microsoft on board, U3 required a software install to be able to work on a PC, kind of defeating the purpose of U3. In theory, this is still a great idea, so hopefully SanDisk and Microsoft will get the new standard out soon.
