Hard disagree. My first phone was an iPod Touch in Grade 4, and by Grade 5 I had already jailbroken it with one of my friends. By Grade 6, I built my own computer, got a phone with data, and by Grade 7 was running Linux on my desktop computer, which I used in Grade 8 to compile an Android ROM from source. I'm now an intern for an Android app development company. If I didn't get a phone until Grade 8, not only would I have had way less exposure to technology as a hobby, but I wouldn't have been able to enjoy playing mobile games with friends.
