Amusingly, I found myself with time to kill at a B&N last weekend and went looking for the SWSE, only to be (initially) disappointed as they didn't have any. I checked with a clerk who insisted they had one copy on the RPG shelf.
After digging around, they did indeed. But their RPG shelf is arranged with the covers of the books facing out (like a magazine rack), and someone had placed a book in front of the SWSE copy, hiding it from view because it was so short.
I didn't pick it up -- paying retail is a bit much for something I'm not sure I'll use. I'm still on the fence -- for every thing I read that I like, I read something else that I don't. I was hoping to get a chance to play it at GenCon, but that hasn't panned out.
