N9 was very close to launch when Elop came, so that went ahead, but the rest of the development got cancelled immediately to focus on Windows phone: N9 would've otherwise been the first in a series of devices to slowly take over from Symbian.
Until Elop canceled everything Symbian was still selling - declining sales, but still millions of units. So while the situation was bad slowly phasing out Symbian for taking all the money you could make with that, while hoping N9 software stack sticks sounded like a more sensible approach than "cancel everything, go for Windows". Elop did respond to criticism from Developers (including a mail I've sent him with colleagues), but had made up his mind.
This blog post is a byproduct of that discussion, and was referenced by Felipe in internal mailing lists back then:

I have no idea how successfull it'd have been in the end - the UI was great, parts of the softwarestack were problematic (though we've been doing quite well with parts of that at Jolla later on). The planned hardware for the future models was less than ideal, though.
Elop was the trojan horse that killed Nokia. He worked at MSFT prior to this and single handedly destroyed Nokia. The N9 was revolutionary on its own; GPU accelerated UI, sleek looks, Maemo OS, it is a device people would actually want over the limping Symbian that never fully adapted to touch-only, or the useless Windows Phone 7.
No developer dared to touch Maemo because its future was so uncertain due to the switch to WP. My dad was one of the early Lumia adopters and it was so limiting in what it can do.
