Unfortunately in current state of Jolla I can not do without the power button:
- while locking by swiping down from top is great(and natural in a gesture based UI), it has at least 2 shortcomings:
a) when holding the device with one hand it is quite hard to reach the top and perform the lock gesture
and
b) when you are using an application(e.g. Twitter) swiping from top will close it, so you have to swipe from the side, then swipe from top lock screen. Instead you can do just a simple key press.
- I envy the stability you have with your Jolla: since 1.0.3.8 I barely get 2 days of uptime, due to random reboots&shutdowns(and no - I do not use Android apps, I even do not have Alien Dalvik installed).

So I can't see power button going out of use for me anytime soon. Actually in 2 months I have rebooted my Jolla more than my N9 in 2 years. Hope that upcoming 1.0.4.x will change this.
