Yeah it is a bit buggy (crashes randomly every once in a while, side swipes sometimes stop working, notifications stop showing up, no notification screen) but it (kind of) works! I was pleasantly surprised with it (not bad for Alpha version) and I'm using it purely as an email-checking-on-wifi device. My N9 is unusable for email now.

I got the apk from the XDA thread I'm using it on a galaxy nexus with a freshly flashed Paranoid Android 4.4 ROM.

Jolla releasing the launcher is a good thing IMO because it got me excited about Sailfish when I was just about beginning to get tired of it. I can't wait for the HADK to be released now.

OT: Anyone manage to get Ubuntu Touch (trusty) running on a Galaxy Nexus? I've tried and failed multiple times.
