I have a preorder for the Nike version in silver/silver. I noticed that best buy has 2 day availability for AW2 in space grey with the grey with the woven band (apple inexplicably says 3-4 weeks). i'm a bit torn. The Nike version looks awesome but it also looks unusable in a work environment. I am not a serious runner - just a weekend warrior type. From what I can tell the Nike doesn't offer any real improvements over the regular AW2. And, I would probably prefer a more flexible version that I can use for work and gym. Stainless steel is out of my budget. I really like the aluminum silver and silver woven band but that one's not available. Wait for Nike or pull the trigger now? Is the Nike strictly for gym use based on the look? Can the bands be swapped just like all AW's for a more conservative look during the week?
