Conclusion

Smart glasses are the new up and coming technology.  Just like cell phones, they have the ability to access information on the go, like GPS and emails.  They also have the ability to record video and images at the simplest voice command.  All of this can be done while wearing a simple head piece that look like glasses.  This kind of technology comes with issues and concerns, much like cell phones did.  Safety is always important, so driving while operating these glasses is a valid argument.  Privacy concerns, such as being recorded by a stranger, are also legitimate.  The technology is not quite ready for wide spread general use, or even specific functional use within specific industries, but it is being refined.  It won't be long until everyone has a set of wearable computers.
