I can easily see how he could have these problems. His use case is ridiculous.
I can't imagine a sane human being putting on Google Glass and thinking "hey, I'll watch video or read web pages on this thing!" That's almost the opposite of a normal use case. I can't imagine looking at the screen for more than a few seconds at a time.
The value of glass:
1. Non-distracting notifications of emergent information
I don't take my phone out of my pocket every time it buzzes. I don't constantly read twitter every time I happened to pull it out to see what that buzz was. Instead, I just live my life. If I'm walking somewhere, and glass buzzes, I can, at my leisure, cock my head slightly to turn on the display and read the message. If there's a short followup, I speak it into Glass. If there's a long one, I, at my leisure, deal with it later on my phone.
I'll be honest. For driving, or especially biking/touring, the turn-by-turn is worth the current price of admission even if that is the SOLE use. Trying to mount a phone on a motorcycle/bicycle, let alone pull a phone out of one's pocket while biking, is laughable. The navigation is amazing to behold the first time you use it. For a frequent biker/traveler, it's already indispensable/
3. Candid photos
I have a large collection of interesting shots of my life now. The photos are indeed at an "angle" much of the time. Who cares? If I want to take a picture, I use my phone, or a real camera. I use Glass solely to catch, again, emergent moments. Something interesting happens, and I snap a photo discretely and immediately. For that use case, I defy a regular camera or smartphone to be deployed and used quickly enough without similar "angle" or "shot framing" issues.
Glass is primarily a notification tool coupled with a navigator and a quick-draw smartphone.
I'm not saying Glass is perfect. Far from it. It has a long way to go. But this guy appears to be trying to use it in the least imaginative and least useful ways possible. He's doing the equivalent of complaining that he cant edit 4k video on his phone, or that he can't easily make toast with his flamethrower.
