Tizen may mean "eleven" in Hungarian, but when it's phonetically spoken outloud the English word "teasin'" (teasing) comes to mind. I guarantee you that will become a wordplay in the press that won't look good for the new OS (the way "Ovi" went over very badly with English and Latin-derived languages speaking countries). They really should reconsider the name. Quickly.
The whole Tizen thing is actually a bit funny because Nokia whined a long time before they were allowed to call Harmattan Meego. I bet qgil and other Nokia dudes didn't see this coming. Or anyone else for that matter. Now what's next? The N9 being delayed a few more weeks because they must make new boxes marked "Tizen 1.2 Harmattan".
