I'll probably switch to Lumia 830 in next few weeks -- the problem lies in amount of email accounts I have to manage -- 5 exchange and 3 gmails, no viber and tresorit, that company choose over skype and dropbox.

So many accounts were too much for poor N9 and when removed all email and messaging except SMS/MMS, no syncing whatsoever, it's snappy again.

As for Jolla -- it excells as wifi hotspot/modem + I use it for geocaching. With no voice calls and only data transfer battery seems to last forever.

Have no intention to sell N9, will join E7 and N900 in my hall of fame
