I only met up with a Jolla owner and played with it hands on.
I did pre-order it before and ended up cancelling it.
So my experience with it is very limited. And the Android compatibility always seemed lacking.

The BB Z10 was also a let down in terms of the Android compatibility.
It was a little more responsive, and not too buggy.
But compared to a native Android device, it can't compete.

However, using both devices natively is kind of weird.
The Z10 is very smooth, but the Jolla is smoother. Sometimes launching something takes longer on the Jolla than the Z10.

But overall, (native) Jolla felt like iOS smooth. And the Z10 felt more like WP smooth (quite smooth, but "could be better"). However, their Android compatibility experience is the opposite. With the Z10 feeling like a 4.0.3/NOTE era-device. And the Jolla feeling more like a 2.3.7/Nexus S era-device.

With that said, the BB Z10 does have more RAM and a newer/faster/better Processor.
So if the Jolla had the guts of the Z10, I think they would be equal, toe-to-toe.
The only thing that affects the BBX/Z10 is some extra features and security built into the OS, which slightly bloats it up compared to the rather clean SailOS.


With that all said and done, I think we need a modern SailOS phone.
The Nexus 5 is a great idea, but they treat it more as an experiment rather than a legitimate approach.
A final/stable build of SailOS would scream on the Nexus 5. And offering its much quicker Linux + Qt architecture would put the traction on that power.

I'm talking 2010 Core2Duo desktop performance, right in your pocket.
