3 reasons why putting facebook button on smartphones = terrible mistake

1. It is FUGLY: the icon makes the entire interface look unbalanced. It looks awkward.  Not only it doesn't look like it belongs there, it draws your eyes away from the rest of the beautiful hardware design. Android phones are already cluttered with 3 more functional buttons than iphones...Look at iphone, clean front face design. Look at us, we've got the htc logo. It's cool, it's cool. Just put mobile carrier's logo on the back... and that's it right? doh! facebook logo wants to join the party too!? shit! Way to go! Way to go! Way to make a nice and clean design that is appealing to consumers! DO NOT WANT!

2. Look at me! I am a facebook whore: facebook is addictive, and it is a great way to "check" what your friends are up to. I just can't imagine anyone wanting to walk around with these phone, and flashing them in front of new friends.  It's like screaming to them, oh hey let's add each other on facebook, so I can stalk you 24/7.

3. Unnecessary user experience: We arguably have to move our thumb all the way down, click, and then move all the way back up to navigate around on the screen...

 “The quick-share button will actually glow when you’re in an app or feature that allows you to share what you’re doing whether you’re listening to music, browsing the web or swiping through photos. If you press and hold it down, you can check into a location with Facebook places.”

Privacy man! What if we hit the button by "accident" ... and shared something we didn't mean to share and then find out later. Let's say Bob went to a local strip club, and accidentally hit the facebook button. Oh!!! Now everyone from facebook know he's getting a lap dance. How embarrassing! Seriously, it doesn't take that much more effort to click on the facebook icon for the app in the interface, and manually update facebook ourselves.

Final word:
Look, HTC. All smart phones has facebook apps...If facebook button is necessary to convince "smart shoppers" that these are the phone have deep facebook intergeneration, please consider at least blend in the design a little? Or just put a big facebook icon in the sense UI?
