It makes me recalled the time when I was studying in China. There was a class teaching us that the future of the world will be resources communal shared by everybody equally. I didn't understand that and no way to believe that. The core of that theory is free for everything, the true free. Are we moving that direction? Of course not, but the opposite way!

Everybody likes free, but the "free" for what we are giving today are not the true free. It's a potential trap to lock you down for a sale behind the "free". Google is the biggest free trapper in the world!

That's right, there is no free lunch, and we all know that. But it seems that people like to be trapped. It's a new trend with sales of business model.

Wenjun:
An excellent observation. It reminds of the old adage, "you get what you pay for!"

I believe the world "you get for what you have paid". When you shopping, sometime you will be facing the decision of buying a cheaper one or expensive. Cheap means lower quality and nobody wants to buy bad quality stuff. Expensive one usually good, but cost more. I don't know how you guys handle that. To me, I'm kind of person to choose the middle one. I know someone like to buy really good one and wishing to keep it for long.
