It has been a long standing tradition for every release of Microsoft Windows to be accompanied by unofficial anime mascots called OS-tans. Windows 7, which is scheduled to be launched in a few weeks time, is no exception.
However, whereas previous Windows OS-tans were mostly grassroots creations by amateur artists within the community, the Windows 7 OS-tan was created and officially endorsed by Microsoft in Japan, and has started appearing in marketing promotions for the new operating system!
The Windows 7 OS-tan, named Nanami Madobe (窓辺ななみ) and whose name includes both the number seven (なな) as well as the character for window (窓), even has her own Twitter account. I mean, which mascot doesn't have their own Twitter account today?
Final bit of trivia: Believe it or not, Nanami also has her own voice actress. And her voice actress, Nana Mizuki (水樹奈々), of course has the number seven in her name as well (奈々). Coincidence?
