The article is kind of a fluff piece in general. The kind of thing where I wouldn't usually bother reading more than the first paragraph.
However, I choose to read the entire article so I could comment and no one could fault me for not reading the whole thing.
The phrase "relatively huge success" bugs me.
Huge means extraordinary..., exceedingly..., mammoth..., unusually great....
Relatively means by comparison to....
To justify the use of "relatively" we need to compare the iPhone's success to something so we can call it huge, but I can't think of anything. I would qualify the iPhone's success as "good" or "better than typical/expected".
If the author was thinking of something in particular to compare it to then it would have been good writing style to mention it in the article, as your typical reader probably doesn't have a ready reference.(example: "compared to other smart phones")
My interpretation:
To me, it seems likely that the author was using the phrase to generate hype or a sense of urgency for his writing(an effort that feel flat on its face).
Less likely but even worse, the author was attempting to pad an already fluffy article.
Either case is disappointing at best.
TG, I expect better.
