It's hard for me to fathom that the iPhone is nearly 10 years old. I remember when I saw a first generation version for the first time. I was standing in line in a roller coaster queue, and a guy in front of me had one. (This was before Apple Stores were in my area.) He happily demoed it for me and I was fascinated. I had a little Palm PDA, and the iPhone put it to shame. It's interesting that while the hardware has evolved considerably, the interface is still pretty much what it was a decade ago.
