Got a TechTarget email about the 12 types of annoying cell phone users. While I don't find them annoying in general, every once in a while I get a "Grrrrrr" moment.
That led to me the slide show of the Mobile Phone in pictures at http://www.cio.com/article/504135/The_Mobile_Phone_A_History_in_Pictures. Since it's a flash to the past to see all the old cell phones and try to remember "Did I ever have that one?", I'm putting up the link to it too.
