That sounds like it would be "tech savvy" to someone who probably used computers at work at least half the day, and is constantly sending and receiving texts from her son on her cell phone. When my sons were 13, I would have considered them to be tech-savvy. The older one had taught himself 3 programming languages by that age, knew how to find and use proxy servers (before the internet had been invented), and a lot of other things I had no idea how to do. The younger one wrote his first computer program before he started kindergarten; it was very simple, but it worked. Before he was 3, he could find the cassette with a game he wanted to play, put it in the player, load it, run it and play games, make music or pictures, and practice typing. By 13, he had helped me build one of his computers, was able to upgrade memory in it, replaced the modem and other repairs. I won't even start with the things they can do now that they're adults. Yes, tech savvy is relative.
