I'm not sure, I felt (and feel) the same way about tablets, and about smartphones except in limited cases. But tons of people got them and now they're standard.
So I wonder if a good litmus test for this sort of review might be to find/replace Glass with iPad and see if any of the criticism doesn't apply. Very little in the article seems to pass the test, so even though I tend to agree with the sentiments, I'm not sure most consumers will feel the same.
