I pre-ordered the SG because I didn't want to spend a lot on a 1st-gen product. I even did a try-on, and was convinced I made the right decision.
One week after receiving the SG, I began to wish that I had gotten the SS instead. I do like the SG, but I was thinking of the "classiness" of the SS. It didn't help that this forum started talking about the benefits of having sapphire glass. I looked at the SS at my local Apple Store, but did not have a try-on. I was torn. Unfortunately, if I ordered a SS now I would get it in July. I did it anyway, a SS with Black Sport Band, which delivers in July.
Since that time, I've grown to be content with my SG. I backed the Click adapter from Kickstarter, and chose their steel and leather bands. Maybe that will add some "class" to my SG. The SS I ordered still says July, but I won't cancel it. When I get it, I'll decide again. But for now, I'm sticking with my SG.
