Apple would have inevitably done their own thing, but it would have been really nice to have two widely used, mature and open mobile Linux platforms.
And that's precisely why companies nerf their web sites and put a little popup that says "<service> works better on the app".
Hit ctrl-f and typed Meego as soon as I saw this thread, hoping I'd be the first. Alas.
The N9 was literally a vision from an alternate timeline where a mobile platform from a major manufacturer was somehow hackable, polished, and secure. Favorite phone I've ever owned and I used it until it started to malfunction.
Had a Jolla for a bit, too. It was nice to see them try to keep the basic ideas going but unfortunately it was a pain in the ass to use thanks to their decision to go with a radio that only supported GSM/EDGE in the US. Had to carry around a MiFi just to give it acceptable data service.
I think the idea with Jolla is that if Nokia ever did an about-face, they were ready to be reabsorbed and get things back on the right track. Unfortunately, though we do once again have a "Nokia", it's just another Android white label with no interest in maintaining its own leading-edge smartphone platform.
