Oh, the article is just painfully wrong. Chiclet keyboards were all the rage in the 80s, when cheap keyboards were needed for cheap computers. That's where the term seems to originate from, as well as the conotations when calling something a chiclet keyboard--it's just absolutely horrible.
Apart from that, there are two advantages of "modern" chiclet keyboards over traditional scissor-switch keyboards (the older ones were really crappy, so let's not talk about them).
Advantage 1: They look quite nice.
Advantage 2: More usable key surface due to lower space between keys required.
But there are disadvantages:
Disadvantage 1: It's utter crap.
Disadvantage 2: Keys aren't sculpted, so your fingers won't find the center to hit them. Keys are sculpted for a reason, mainly to guide the finger. If you remove the sculpting, the finger isn't guided any more, which is quite bad.
I don't think the looks are worth this, as typing comfort is much worse than on keyboards with sculpted keycaps. You'll hit the keys at all kinds of weird angles and spots, and they're generally just a pain to use.
