The difference is the original iPhone was actually useful for things people actually wanted to do, and reasonably priced for those uses. They sold 1M units in the first quarter, making it one of the most popular phones in the world at launch.
Apple spent many years creating the iphone. First they created a tablet computer, Jobs rejected it as not ready, not good enough. They then built a phone based on ipod touch wheel. Jobs rejected it as not good enough. He let the tablet team try to build a phone and eventually after much work and improvements, finally shipped it because it actually worked well for consumers, and could do many things consumers wanted (phone, texts, music, web, etc)
Google got glass working and said, what's will consumers use it for? We don't know, so let's dump prototypes on developers and have them figure it out!
Eventually some company, probably Apple, will build something like Glass that consumers will want, but it won't be Google. They don't get consumers (except for high functioning types) and their product development/approval process is a mess.
