Please no carbon fibre, it screws with wireless signals, especially wifi, just ask any vaio pro13 owner, it does not bode well for reception. I'd also prefer a metal and not glass since glass can pick up too many fingerprints and can break where as a nice mat metal is stronger and leaves less fingerprints.
No, no, no! That's backwards. Carbon fiber is (mostly) an electrical insulator. It DOES NOT conduct electricity, but metal does. It is metal that interferes with cell signals. The carbon fiber phone will have much better signal, all else being equal.
I really hope Sony does not downgrade to aluminum or any metal. Poorer reception, doesn't look as good IMO, kills the ultra-premium vibe of the phones. Also, aluminum scratches much easier than the glass Sony uses.
Sorry I don't believe this, I own a vaio pro 13 and the wifi reception is piss poor on it, apart from a shitty wlan card, the antennas in the screen are covered by the carbon fibre, as is the rest of it in the body. I lose wifi signal really fast with my pro 13, whereas my galaxy S2 which is now I think 3 years old? has much better reception than my vaio.
CF seems to absorb the signal and not block it, so this is why the reception is altered.

Honey, you can "call BS" on it all you want. You're arguing against physics, and OLD physics at that. I'm sorry, I'm telling you, as a guy with an engineering physics BS, you're just wrong. Carbon fiber, depending on its exact configuration, either doesn't conduct electricity, or only conducts it along tangential directions. Metal, on the other hand, is a conductor by definition.
I don't want to get into the philosophical reasons why inductive reasoning like you're doing is generally invalid, but suffice it to say you can't take one product and then draw conclusions about different classes of materials. There are many things that could be responsible for your Vaio's poor reception, and you can't just arbitrarily pick one thing and blame it all on that.
Look up "Faraday cage" on Wikipedia if you still don't believe me.

it looks like some kind of metal too me!

Carbon would absorb only a very, very small amount of the RF signal's power or probably not at all, so very little attenuation there. Metal, like aluminum, would also absorb very little (probably a bit more than carbon) of the signal BUT it is highly reflective since it is a very good conductor and that would heavily attenuate the signal.

Removing the Wifi antenna from pro 13 and exposing it drastically improves the wifi reception on the device, so there's that.

By the way, look what just came in the mail!

Of course it would, then there's probably something blocking (reflecting, actually) the signal from the inside.

Not to get all pedantic, but conductors don't "reflect" electromagnetic waves. The electrons, which by definition are free to move in a conductor, are moved by the EM wave into a configuration that cancels out the EM wave. This is why conductors shield EM against EM radiation.

@Wintermute
You'll love your MDR-1R. By far one of my favorite headphones out there!

Err, my physics knowledge is not that deep, so at my level (probably way too shallow than yours) I think of it as being "reflected".
