I have a S0 SS. It has held up so well for me. I have pretty much destroyed everything from clothing to bikes and skis my entire life. I just picked up an aluminum S3 for my wife. It looks great. For her I expect it will last indefinitely. If I felt confident I could do the same with the aluminum S3, I would buy one immediately. The premium of the SS is hard to justify. But there's also me in the equation. I haven't decided yet. So far the performance, in all ways, of the S3 is hard to resist. And for one who loves to pursue activities without a phone, the LTE version is a no brainer. I am so torn here. Nothing about this choice -- nothing -- has to do with appearance for me.
