SanDisk announced a significant enhancement to its line of Cruzer Micro and Cruzer Titanium USB flash drives. The two models feature a sleek new design and include software that turns them into “U3 smart drives” so users can access their “personal workspace”–software programs, personal preferences, personal files, and data, as well as the means for managing them within a highly secure environment–on any personal computer running Microsoft Windows XP or Windows 2000.
