I think I must be alone in this, but I think the Xbox one looks pretty darn good. Could it be better? oh god yes. Better built, definitely. But I like it and here's why.
Each console that comes out is ugly. Yup, not just ugly, fugly. Go as far back as your age allows. Atari, intellivision, coleco Vision, NES, SNES, N64, Cube, PS1, Saturn, you get the idea. All ugly. My opinion of course. Why do I hate them all, because they always looked so out of place with my AV gear. They also usually are some odd shape or design that doesn't fit on or near anything but on its own shelf and they've always been a pita to find a spot for. Now I don't recommend stacking anything on or around a console but I hope you get what I mean.
For once, even if it is just a plain rectangle box, it doesn't look out of place with my gear. Does the Ps4 look cool? I guess so (granted the two I have were DOA) but I think the PS4 is going to have some major cooling issues given its design, whereas the basic design of the Xbone looks like it is at least vented well. I should mention that I haven't actually gotten mine yet, so I may change my opinion when I hold it, but from what I seen, I like it.
That being said, the Xbone green box...is absolutely fugly. Horrible, plain, non-inspiring etc.
