I don't see any problem with their line of reasoning. I think you are being dumb in your reasoning. The first iPhone was sold very quickly to early adopters. Apple, having pretty much no experience in the cell phone world, has been learning as they go, plus they had to rely on other chips makers in making cell phone chips. But they constantly improve up their design, year after year. Sure, they don't progress as fast in certain areas, but let's look at the Nexus 4 and SIII, those both have terrible cameras, terrible battery life, buggy OS. the iPhone 5 is a vast improvement over the very first iPhone and I'm sure Apple is working on potentially several sized versions for this year's models. I think they will come out with larger screen models as demand for iPhones increases, they have to see what kind of demand there is for various screen sizes. Since the 4.5in and larger screen sizes are gaining ground, Apple can justify putting out a larger screen size, but a year ago the larger screen phones weren't selling well. The 3 III was the first large screen size phone that sold well. The S2 didn't sell that well and neither did the first S model.
The cell phone industry has gone through changes largely due to the different technology in networks that are being deployed, it's a nightmare to keep on top of it, and everyone is relying on only a couple of chip mfg for decent voice/data chip sets.
Now with these Google Glass, there are going to piss off a lot of people because people, on average, do NOT want someone with a video camera facing them while they are in a discussion. I certainly don't. I don't want some a##wipe immature brat with a set of these things video taping and posting on YouTube videos of me.
I think Google is going to be in for a little shock when they find out that they will be banned in a lot of places. There are privacy attorneys that are trying to figure out a way to prevent these things from being used.
The OP was criticizing Google Glass for being an immature technology and I claimed that the original iPhone was immature as well. I was making a comparison ...and you apparently agree with it based on your first paragraph above. So exactly why is my post "dumb" given your alignment with what I was saying?
Also, regarding the privacy issues... you may be right that people will feel uncomfortable talking to others that are wearing the Google Glass. But remember that any " a##wipe immature brat" can record you today as well with current smartphone technology, without your consent or knowledge. At least with the Google Glass, it's apparent that you are recording (a light appears on the Glass device so others know it's recording). This is mentioned in the Verge's article.
The iPhone on the other hand has no indication that it's recording a video; unless you're looking at the iPhone's screen, you wouldn't know a video is being captured.
