If Nokia releases a Meego phone that can compete with iOs and Android.. it will sell.

The tech blogs will rave about it, word of mouth will spread and it will sell like crazy...

But to sell like crazy (mass market), it has to
- UI has to be buttery smooth
- the maps app like has be as good as google maps (smooth UI, 95% accuracy in search results)
- out of box apps, facebook, youtube, email, twitter, internet radio have to polished
- dev support out of the gate, docs and apps to write apps from windows, linux, mac

If its none of the above, it becomes plainly obvious why Elop had to make the swtch (i.e Nokia engineering first (who cares about usability) culture simply cannot be changed)
