Are You Annoyed By People Using Cellphones At Concerts? [POLL]

Cellphone use has increased astronomically over the years and looks to only get worse, people are literally stuck to their phones.  People are constantly texting, calling, surfing and taking pics, and one of the worst times to use a phone though (in my humble opinion) is at a concert.   I hate trying to watch a show over a sea of cameras taking videos and pics.  

At a recent Eagles concert it was announced to the crowd that cellphones were prohibited and not to be used.  This obviously pissed off some people who feel it's their right to bring a phone to take pics/videos.  But isn't also the bands right to ask that they not be used?
