Right on...non removable batteries- production costs reduced, but phone prices rise sky high anyway; Apple's trend unhappily kicking in..I hope you do realize that water resistance is just an excuse to make the battery non replacable.
Programmed obsolescence is made SO MUCH easier when the battery is more difficult to change!
Another great feature is also gone on the V30 and that is the IR Blaster that I got used to.. I installed a great remote control app and I have control of almost ALL my devices ( TV, stereo, home theater, air conditioning, you name it) just with my V20. Great when you can't find the original remote controller, or the wife is monopolizing it, or making pranks on friends's houses or other places..
Gonna hang on the V20 for a loooong time!
