Except that Google has been in development of Google Glass before the iWatch was even rumored. So perhaps it is Apple following the leader again. The iWatch hasn't even been unveiled so how can Google be reacting to something that doesn't even exist and wasn't even rumored at the time they created their product? I'm sure the fanboys though will try to rewrite history again like usual.
Sorry to break it to you, but here's Apple's patent from 2006 (before iphone) on their own head mounted apparatus -- however, google is obviously more vocal about their project.

Also, don't forget the guys in Redmond are also working on their own apparatus says their 2011 patent, but again google is obviously more vocal about their project.
