I have the 128 GB Space Grey Wifi+Cellular iPad Air with Verizon Wireless 4G LTE. I got it to match my iPhone 5s 64 GB in Space Grey with Verizon Wireless 4G LTE.
I don't like the White and Silver color for Apple's iPads and iPhones, but that doesn't mean that I haven't debated whether or not to choose it as a color for my next iDevices, whatever they'll be! To me, the white and gold are just too flashy. The Space Grey color is slick and refined. Much better than the Black and Slate color on my iPhone 5 from last year! The main reason is that the Space Grey 5s that I has not gotten any scratches, while my iPhone 5 got a lot of scratches even when it was in the case.
