Well, I'm doing it the other way: from BBOS10 to Jolla I used the BlackBerry Q5 for a good while, and to be honest, the BBOS10 is really a good mobile operating system. The HUB itself is worth everything. But it's a very "sterile" system, there's no way to touch the sytem or alter anything. Soon I found myself installing the new and newer "leaks" to get something new.

I can't comment on the Jolla yet as I'm only using it for 3 days, but so far I love it I love the asthetics of the OS, it's so good to look at it. Of course I'm handicapped as I got used to the BB gestures and now I'm always checking the notifications instead of minimizing the apps, but I think it's just the firs few days... Of course on BB10 there's a lot more native app, and there are basics missing from Jolla's store (e.g.instagram alternative for one ) but based on my limited testing the droid apps starts faster and works faster on Jolla than on the Q5...
