The author of this article does not present 3 inconvenient truths, what he actually presents are 3 personal opinions.
#1 opinion = I have wrists like ham hocks and therefore Apple made an epic fail by not making a watch big enough to look proper on them.
My opinion= I measured my Pebble watch and it appears that the

Watch is slightly larger then it. Also I may be wrong here, but are not screens measured on a diagonal? He puts length & width but not the hypotenuse.
#2 opinion = is just that, an opinion. He is complaining about things being too perfect, not being made the the way he thinks they should be. The straps are too perfect. There's no stitching visible on the leather straps.
My opinion = this whole watch is something new. Nothing about it goes by past standards. He's complaining that Apple has found a way to manufacture a leather strap without any stitches or apparent seams. Stitching and seams on a watch band can feel uncomfortable to some people, but in order for Apple to please him they had better put them in. Even if they are not needed any more. Welcome to the 21st century. The times they are a changing.
Opinion #3 = Here he complains about the screen being not clear enough for his tastes.
My opinion = In opinion #1 he complained about Apple using close up photography to make things look larger. Now he resorts to the same blown up photos to attempt to make his point. And his photo, in my opinion, has too much light glare in it to use as a point in his argument.
There are no inconvenient truths in his piece, only his opinions.
