While I still consider Glass to be a solution without of problem, unless people use and find problems with them, innovation will not occur. There is a process of failing that precedes success. I understood when I bought Glass there would be issues. I wear them to find these issues and attempt to improve them. That is why I love to program. I like to make things better.
I read the complaints on the Explorer board, and I am shocked that people expected a perfect product. This is meant to be beta testing. Google has been very clear about this.
If you don’t wish to seek innovation, and you are afraid of things not going perfectly, send them back. You are probably not the type of person who seeks to improve the world around them.
