There is a new cell phone on the verge of being marketed. It is made of paper and will be sold from vending machines. Its cost will be about $20, which includes the phone as well as 100-200 minutes.
Once you use up the minutes you just toss the phone in the trash and buy another one.
If you have heard of this new product and know who makes it let me know. I like the concept and think it has potential.
