Mod the parent up.
My smartphone“ (an iPhone in my case, but to be honest, something running WebOS, Android or Windows Phone would also work) is a lousy phone. My cheap Nokia work phone is far better. In fact, every cell phone I’ve ever owned has been a better phone. I don’t really care because I average 1 minute a day talktime and most of that is with my wife and kids; logistical syncing stuff. I was late to the smartphone bandwagon because I lived like the OP for many years; using an old clamshell with a dirt cheap voice only plan.
Holy cow! I’ll never go back!
I’m increasingly finding that my phone is replacing my laptop. Many tasks that I used to crack open the laptop for, I can do perfectly fine on the phone and for serious work, I’ve always preferred desktops for real work anyway. So basically, it’s a substitute laptop that fits in my pocket, has internet access wherever I go and a GPS built in. And that GPS has a standardized API, so many of the applications on my little pocket laptop are location enabled; from the useful (such as finding the highest rated restaurant within walking distance, or checking on traffic info) to the useless, but fun (such as finding out about that airliner flying overhead; which airline it is and where it is going).
I could even put an ssh terminal on it if I had need of one.
And I pay about €20 a month for it. Are service plans really so expensive in the US?
