Technology Getting Smaller

So I was looking on the internet at some new technology and I came across a few interesting articles. I was reading about the new blue tooth phones things and they said they are making them even smaller. So now I am wondering how much smaller is technology going to get before we stop. Those hand held computers we looked at in class were so small. I think technology has gotten small enough. Like i am a big guy and all these little devices are hard for me to use. Those crazy little computers that you cant even push the buttons. I think everything is small enough and like why make things smaller because they are so expensive and the smaller they are the more likely people are to lose them
