OpenOffice 2.0.1 now comes on a flash drive–but an analyst claims the software is too bloated to be truly portable. The latest version of Portable OpenOffice.org, an edition of the open-source office suite fits on a USB stick. It includes a number of updates, such as full support for Windows 2000 and launchers for each OpenOffice.org application. But 144MB is still too big, considering that many USB sticks only store 256MB, according to Gary Barnett, a research director at analyst firm Ovum.
