Repassando a nota oficial:
“According to Information Week, IBM has introduced a line of business computers that avoid Microsoft’s desktop environment in favor of open source software. IBM worked with Canonical and Virtual Bridges to create the platform, which IBM claims saves businesses $500 to $800 per user on software licenses and an additional $258 per user ‘since there is no need to upgrade hardware to support Vista and Office.'”
