>You missed my second statement, I think.

I didn't. Nothing in my post could possibly make any reasonable person think I missed it. It bears no connection whatsoever to it, nor does it contradict anything I wrote.

>social networking has the same effect on a laptop

You carry your laptop literally everywhere you go and use it in every imaginable situation you can find yourself in for more than six straight hours every day? You really pull out your laptop while waiting in line at the grocery store? You text on it while driving? You use your laptop strolling down the street at any given moment, or at restaurants with friends, really?

Get real.
