I'm also using the Nexus 5 and can confirm all the bugs above.

My N5 actually cost me half as much as I paid for the Jolla (£110 on eBay from china - had to wait a few weeks but the device is genuine!)

Despite those few bugs listed above, it's a much nicer device to use than the jPhone (although the screen is bigger the phone itself is lighter, better battery, I can run more than 4 apps without having things force close, way faster, better camera). In addition, if Jolla goes under (hopefully not, but possible) I can run Ubuntu Touch or any other OS that uses libhybris on it.

Worth checking if you can get one cheaper on eBay, though I appreciate it might not work out to be cheaper due to import taxes etc.
