anyone else feel the travel on their iPhone 5S's power button is less than previous models? for those unfamiliar, what I mean by travel is, does it seem like the power button sits lower inside the top of the phone and does not go in as far as previous versions? I know this sounds like nitpicking but I haven't had a chance to go to my Apple Store and check the display models to see if this is normal...I feel like the button requires extra pressure and sometimes feels like it doesn't have that satisfying "click" to it. If this the case with all the new 5S's, then maybe this is a more robust design aimed at alleviating the previous power button issues?
