Tech-Savvy

There were 2 articles in this weekend's Minneapolis Star-Tribune that caused me to think this weekend. One was about someone who quit Facebook and the other was about travel help for folks who use their cell phones more than I do. What got me thinking was "Tech-savvy" in the headline.
When it comes to technology, I am not a dinosaur, but not exactly cutting edge either. Most of the "Things" that MILI has covered are either new to me or things I knew about but elected not to use, like Facebook. There is so much to learn. And just when you learn something inside and out, it changes. So I read the article "Travel help for the tech-savvy" very carefully. I expected to run into something from this class. Instead it featured Text messages, GPS, Google Maps, Yelp, iWant, UrbanSpoon, OpenTable, Widitude. All cool. All new. More stuff.
Meanwhile, I decided to see if a friend was available for lunch tomorrow. I had to look up my cell phone number. I don't have texting or photo features.
So I wonder about the things in the article--if I had that kind of phone. Like, do you have to purchase those things or do you just download them? How much money a month do teen need to be "Tech-savvy?" How do you download to a phone?
And how much of all the tech stuff do you have to know about, use and understand to be considered "savvy"? Isn't it enough to just know how to spell it?
