Meet Nanami Madobe, Windows 7 Japanese Mascot
There's a formula that is working beyond belief right now in Japan: mix anything with anime and it'll sell. Just take a look at the Evangelion version of the Docomo Sharp SH-06A cell phone - 20,000 pre-orders sold out within 5 hours of them being available. So if Microsoft has learned anything it's that they need to appeal to the Japanese consumer if they want to maximize their reach.
Meet Nanami Madobe, the Windows 7 anime mascot (note the Windows logo hair clip), and say hello to some high res wallpapers featuring the "OS-tan" at Sankaku Complex (be warned the wallpapers are G-Rated, but the site itself is NSFW!)
