Actually I feel the opposite. The Sport looks plastic and cheap, like a $199-$299 device at best. The SS actually looks quite nice and could warrant the $600 price tag. The issue I have is that I like link bands and the only one offered is $950-$1,100 depending on color and size.
And so I feel that on the SS the bands are overpriced. I hate the idea that tech that by nature has planned obsolescence, unlike a Tag or Movado or other 'timepiece' has such a price to it. One could say "I'll get the Link and when I replace the watch every 2? years I can still keep my band." Except we don't know how well the band will hold up and whether Apple will pull a design switch and make future watches incompatible with current bands.
I will also say as Lefty and someone who really loves Apple aesthetics, I do not understand why the crown isn't centered with the button on the other side. This would make it much more symmetrical, visually pleasing, and make it look identical regardless of orientation.
