Here's a thought: could we combine the best of your ideas (device like #62 or #64 with colors and text of #56)
I temporarily copied and tweaked your designs here:

I think a dark gray (or maybe even black) device, not so big a shell of the device (I like some other designers devices a little better), with the colors and text of #56 included. The blue in the globe would have to look more like sky (keep the blue, without the continents).
