What I've noticed since getting the phone is:
--I DO use it more than I used the old phone, yet...
--I tend to watch my call times and battery meter very carefully
--I try not to use it on the bus or train, so that I don't look like many of the crackheads that do (though that could be just the fact that they're Philadelphians on phones)...if I need to tell Rho something, I'll shoot her a text message (like if the train is running late).
--I tend to "show emotion" when I'm playing games (e.g. Shouting "Yes!" if I get a strike on bowling, though it's more of a loud whisper)
--I get a lot of strange looks when I'm sitting at Market East Station, waiting for the train, playing with the datebook or a game.
I don't really talk a lot on the phone either, but with the new phone and plan, I can:
--Call anyone without disconnecting my modem (and if it's after 9pm or a weekend or holiday, it's free).
--Call someone while I'm out of town without racking up LD charges (e.g. I was able to speak to my Mom and other family members on Wednesday, and didn't have to use my in-laws' phone or LD)
--Call Dave in DC for free (since I believe he has a Verizon phone too, and I have 1000 mobile to mobile minutes that I will almost never use in one month)
--Call people in the Philadelphia suburbs (including NJ and DE) w/o local toll charges appearing on my home phone bill
Every now and then, I actually do something smart.
