... but was wrong :P
It's a subtle point, and won't matter much to users to be honest, but it really isn't MeeGo - it's compatible (to a degree) with MeeGo, but the N9's core OS is Maemo. The most visible sign of this is that N9 apps are packaged as .deb packages, where "real" MeeGo uses RPM.
It's well documented that MeeGo was not in any fit state to give to consumers, and wasn't going to be for at least another 18 months, which left Nokia with a problem - they were spending money to develop a handset, and had no OS to run on it (afaik, Nokia don't have a version of Symbian for ARM Cortex devices, so be grateful that that option wasn't open). The solution was to revert to a known-good OS build, Maemo, and port the Harmattan applications to it. The result is officially "Maemo 6 Harmattan".
The objective wasn't to produce a MeeGo device, but to produce an OS capable of running Qt and the Harmattan UI, which is why the N9 was only ever described as "MeeGo 1.2 compatible", and even that was buried in the small-print.
(btw, I'm male, but you're not the first person to mis-assign my name, and there was no offence taken in any case)
