I have a Blackberry Curve, and I really do like it. I never texted before I got this phone. I, too, have a teen and two adult sons (and their "gals" <g>), and that's a good reason to text. I meet them where they are. I really love texting for the convenience. For instance, yesterday I texted DH to tell them we were at the store next to the restaurant we were meeting at, in case he got there before we saw him. That didn't really merit a phone call, but it saved any confusion if we missed each other.
My BB doesn't have GPS per se (I don't want to pay for it), but it has a Google maps application that knows my location via the nearest cell tower. That really saved me a lot of times when on my trip in September. Sometimes we needed to find a place to stay on the road, and that was very helpful.
The BB doesn't handle documents, either, but I'm never going to need to change one if I don't have my laptop with me. I do blog from it, with pictures, though. I liked that. I do use my laptop less for checking email, because of the email push on the BB. I can at least see if there's anything pressing.
I got the BB so I could communicate better when people walk up to me at the ballpark to tell me they didn't get their uniforms or whatever. I don't have to rely on my holey memory. I just send myself an email or make a note right on the spot.
