Most of my American family and friends do NOT text or if they do, it's rarely. Usually it's to send a picture they've just taken with the phone camera.
There isn't going to be any real agreement here about which country does it more or less. But I get that the UK phone plans make texting cheaper. Doesn't mean I have to like it. But then again, I dislike much about the whole mobile/cell phone culture anyway. Getting into an argument with your SO via text is just stupid - I don't care how cheap it is. But I accept that's my opinion. And if you need to make a call and you're at the pub or the dinner table, you excuse yourself from the table and make a call.
Another reason I dislike texting - we're raising a generation of kids and teens who can't spell or use appropriate grammar. And we're also raising a generation of kids who are used to seeing their parents glued to their d*mn phone and paying more attention to that than their kids. I see that here and in the UK. In the US, IMO, it's people checking their emails via phone. In the UK it's the endless texting.
So yeah, in the grand scheme of things, I *would* rather hear someone making their dinner plans on the phone and overhear a few phone conversations than see everyone head bent over their phones madly texting/checking emails all the time.
But hey, progress marches on I guess.
On that note, I'm going to un-glue myself from this laptop and go spend time with my kids!
