Martin Marty Cooper (born December 26, 1928 in Chicago, Illinois, USA) is considered the inventor of the first handheld cellular phone. Right now, he is using Droid mostly; also mentioned iPhone; and admitted trying every cell phone out.
Cspan: What kind of cell phone do you have?Martin Cooper: “It depends when you ask me. I, always have the latest cell phone, and I try every cell phone out, only because people like you keep asking me. Right now I’m using Droid, because I want to get some experience with the Android operating system, and I so far, have some pretty favorable results. I’ve had an iPhone, which I gave to my grandson, which he used for three months and then I had to upgrade to a better version. And I’ve tried many other phones. For my day to day conversations I actually use the Jitterbug. So I carry two phones, one very simple phone that I can flip open that has a very simple phone book and nothing else. But when I want to twitter – tweet, then, I use my Droid.”
