Problem:
Whenever I sync my iPhone, iTunes pops up and steals the window focus when I am working. It would be perfect if it would stay minimized and sync in the background - there is no way to miss that it's syncing since it even says so on the iPhone display.
This becomes so disruptive to my workflow that I refrain from syncing the iphone too frequently, leading to that my iCal events sometimes arent updated in the phone because I forgot to sync a last time before leaving from work. Regularly, I run out of battery life early because I avoid putting the iPhone back in the dock for the same reason.
Solution:
If this sync dialog could be made less attention-grabbing I'd keep the iPhone in the dock at all times. Very, very easy to fix.
