I think these are two separate photos for the Catholic selection of popes. In 2005 and now in 2013.
Yes, it is different. However, the source link, Soff, has put a negative spin on it. The author went on to say he had disabled notifications on his phone only recently.
I've been doing it for more years. Cuts down on those weird awkward moments and definitely saves battery power too. I know which apps get notifications and which are important that I need to check on a regular basis like my e-mails. Then for the rest, I check on them, like Twitter/Path, when I get bored.
As for the photos, I think it's fine. It's the times and you are your own guide as to how far you want to take your mobile behavior. But I do think that it's good to put away your devices during dinner with friends and family.
