Well... I'm more than likely considerably younger than a lot of you, so I'm going to give the opinion of the "gadget generation" or whatever else the want to label us (tho I'm partly GenX)
I got a computer when I was 12, internet when I was 14 (aaaah dial up!) and I was well versed in my computer. I knew how to do just about everything you could do, both in the graphical interface, and in the command prompt. When I got to high school, I had to teach our computer teacher a few things about computers (she was also our typing instructor and it was the first year that our school had computers, and I went to a smaaaaaaaaaaaaall school!) I still had "a job." I had horses, that and school were all I ever had time for. I earned extra money by going and helping friends train their horses, or cleaning out extra stalls. When I got my license and car, I started slacking. I hung out with my friends more and paid attention to my horses less. When I turned 18 I decided that I was going to get married to a guy I had met on the internet and had known physically for about 2 months. My mom BEGGED me to not do it. Yeah... those of you that have strong willed 18 year olds know that it's almost impossible to talk them out of something once they get it into their heads. Now that I am a bit older (and not with husband #1 any more... egad that was a bad idea!) I had decided that since I'm a single mom, I have no other skills other than being a housewife and training horses, I might as well take my love of gadgets and go to school for it. I LOVED school and all my college classmates and one of my professors decided that, before I had even graduated, that I was what he was looking for in an employee and offered me a contract for $25/hour. I worked for him for a while and I HATED it! Being a (not to toot my own horn or anything) attractive female in an almost exclusively male driven environment was not my cup of tea. Some of those guys acted like they'd never seen a live woman before, and I couldn't handle it and quit.
These days, I'm always connected, but that's how I've always been, even before cell phones were invented. I always knew what was going on, and I always watched too much TV! LOL I have a new android phone, and get a new one every 2 years when our contract allows us to, my husband has a newer android phone but only switched begrudgingly so I could keep tabs on all of his medical appointments, and, we did get our son (who was 12 at the time) a cell phone. He has never been one to talk on the phone, even to people he loves/misses (ie my mom) but once he got that cell phone, he just came out of his little shell and would talk their ear off! He also has difficulty in read (because he's dyslexic) so we do buy him games that have reading in them and make him read what it says on the screen before he can play, he does get computer time with learning specific games. He had to take a course in school about computers and it blew my mind that at his age he didn't know practically anything about computers, but he sure tried hard! Over spring break I'm going to be teaching him a whole lot more about computers. My daughter on the other hand, she is 8 and in the 3rd grade. This year, she is basically doing all of her homework on a laptop that the school provided. She has specific websites that she has homework on every day. She does occasionally get "paper and pencil" homework, but it's maybe once a week. She knows a LOT about computers and can navigate the internet like nobodies business.
Personally, I try to balance electronics and outside time, but.... it's kind of hard to regulate them, when it's difficult at times to regulate myself. Kids do need to know about computers and internet and things like that because it is a computer driven society these days. No matter where you call for any type of customer service it's "let me look up your account on the computer" not like it used to be "let me find your file in this cabinet." There just is not a way to get around learning about computers any more.
