My wife and I just got the latest cell phones when we renewed with Verizon. We're not Luddites, but we do use cell phones primarily for just talking on the phone.
Now we can text message, take photos, take movies, use it as GPS, send photos over the phone, do all sorts of extra things.
Down side is these usually cost extra, and we prefer upfront charges covering everything (duh, even realizing that only the phone companies usually make tons of extra money when many people don't use enough services to cover what they pay for in advance).
I've already found that the cell phone lacks simple USB cord capability to transfer photos to the computer. But of course the phone company would much rather customers use only phone connections for everything.
I couldn't resist springing for a 4GB mini-SD card that costs more than the "free" cell phone upgrade. Could transfer photos and other data to computer with that and its adapter, but the card is so tiny I don't want to handle that any more than is absolutely necessary.
It does seem we're almost into the Dick Tracey Watch era where the phone does everything we need, e.g., no need to wear a regular watch anymore when carrying the cell phone and its world clock with alarm.
After this long-winded prelude, question is: What sort of cell phone services do you regularly use beyond just talking? Any pitfalls you've found? Any supreme advantages that aren't immediately obvious?
