Thanks for the input. I think I'll be pleased with my choice. If not, there's always ebay. ;-p
I actually bought the open box on eBay. The reason I'm not worried about it is because I can return it within 30 days if it has any issues (and that would include anything cosmetic when it arrives), AND because it still has the apple warranty, so if it should have a functional issue, I know it'll be replaced.
I think the overall look for me is going to be better, as I'd like to wear mine with a link bracelet. I want the function for various activities, but I also want the overall look. I've always worn silver watches with a stainless (or similar) finish, so I think I'm really going to like the look. I definitely loved it in store, and the apple employee who helped me had a stainless that she wore with a turquoise sport band (which I have and it's my favorite), and it looked really good. That will likely be the band of choice unless I need to dress it up.
Oh, and it's a 38mm. No way I could pull off 42 on my wrist I don't think.
