With a lawsuit filed in San Francisco, California, two residents of Fostoria, Ohio seek damages and relief from the world's third-largest computer maker after purchasing a sub-$600 Aspire notebook that included Windows Vista Premium and only 512MB of shared system and graphics memory. Microsoft recommends an additional 128MB is required to run the Premium. “A notebook pre-installed with Vista Premium requires access to at least 1GB of system RAM plus 128MB of RAM dedicated to the graphics adaptor to run properly,” the suit reads.
