Google Glass - Would you speak to someone wearing them

There has been a lot of talk recently about Google Glass, the glasses you can interact with the web, record photos and video and possibly lots of other stuff. Here are some of my initial thoughts on this new product.

• How comfortable are they to fit over my current glasses.
• What are the benefits over using my phone.
• Does any images or messages get in the way of reality, could this cause problems for example while driving.
• If someone is wearing a pair, how would you feel speaking to them, knowing that they are recording you.

These are my first thoughts, it will be interesting to see what happens when people start using them.
