So is Sailfish stable enough to use as a daily device? I have three main concerns:
1. Battery life - Is it optimized enough to survive a full day with moderate usage? Nitdroid drains the battery, but MeeGo never dies in one day

2. Is the audio quality good for calling? I use the microphone for calling just as much as I use sms, so I need it.

3. Is the headphone jack working correctly? Does sound route and work? Music player functionality? (I know how to add shortcut to the harmattan music folder, just want to know if it reads all files (flac, mp3, etc))


Also:

What version do I use? Do I use the 1.0.3.7 provided on the second link on the first page? or do I use 1.0.2.5 for right now? If I use 1.0.3.7 do I need the updated kernel, or is that only for 1.0.3.8?

Also,
Forgive the bombardment of questions :P I'm not the greatest at following a thread (especially one that's nearly 175 pages)
