I found this at the Daily Dish.

He's right. I have been on the patio with my laptop, that weighs less than 5 pounds, watching the President's speech from yesterday. Literally a television I can hold in my lap, anywhere in the house, with almost unlimited re-runs. The day I was born radio was popular, and it was the only source of mass media. Today one can buy a laptop for less than $300. With it one can access the Internet and get news, an encyclopedia, and books... for nothing more than the cost of an Internet connection, which can be found for free if one is willing to look.

One of the first televisions back in 1945 was about $325. The price of a bottle of Coke was 5¢, and a Hershey's candy bar was the same. A television was 6500 times the cost of a bottle of pop or a candy bar. Today a can costs $1, so does a candy bar, so a laptop costs just 300 times that of a soda.

So, not only can I do more with this set I have (I looked up all this information on the same machine), but the relative cost is not even comparable. Our children have the world at their fingertips, when back then a set of encyclopedias alone was thousands.

The point is that information technology has come a long way, and it is cheaper now than it ever was. It really is amazing...
