I'd agree to that, and don't have much more to add, actually. Very well put. Stick 'em outside and let kids be kids. Too much tech at a young age can just confuse them, unless they have an unusual aptitude or something.
And frankly, I don't use txt at all - had my phone company disable it. Don't want it, don't need it, too expensive. "Oh", I hear you say, "but you can just get an unlimited txt plan". Yep - for more money. Once again, you have to SPEND money to SAVE money.
Just doesn't make sense to me :)
When someone asks me if I got their txt message, I just say "Sorry, you'll have to actually CALL me".
