Neither your post nor the one you quotes applied logic or common sense. Conclusory statements not based on facts are, by definition, illogical. Satisfied with your conclusion, you skipped the part in the paragraph where you would actually make a reasoned argument and replaced it with a petty, ham-fisted personal attack on those who would presume to disagree. That's the thing about common sense... it's really not so common.
As to the reviews themselves, they're mixed but generally positive. Pretty much all of them cite the Apple Watch as the best smartwatch on the maket. The negatives, such as the learning curve, poor third-party apps, and slow hardware, are typical of a first-gen product in a relatively new product category.
What's most promising, though, is that in the majority of reviews the reviewer ended up loving the watch anyway, despite the fact that the negatives are much easier to put into words than the positives. To me, that says that it actually succeeded in the most important way: it altered the lifestyle of the user.
The potential for future generations of the product to offer additional sensors and software that utilizes them (be it from Apple or third-party) in a manner that enhances health and quality of life is enormous.
I dare say that it's much more exciting than, say, Apple Pay. Interestingly, the long-term success of Apple Pay is probably closely linked to that of Apple Watch, as being able to pay from the watch without having to pull anything out of your pockets or purse really increases the convenience factor of using Apple Pay rather than a credit card.
