It's a shame that so many people like the idea of another aluminum iPhone. Aluminum significantly blocks radio signals. There is a reason that Apple's aluminum laptops have always had the worst Wi-Fi reception out of all brands of laptops on the market. There is a reason that many reviews praised the plastic iPhone 3G's reception as superior to its aluminum predecessor. Using aluminum for the iPhone body would be a huge step backwards.
If aluminum is such a great material, then why do 3G-enabled iPads have those ugly black plastic patches in the back? Oh yeah, it's because aluminum significantly blocks all radio signals, especially 3G signals.
It would be a form-over-function move if Apple decided to make the iPhone 5 backside out of aluminum.
What about Liquid Metal? I personally like the idea of it, and if they made it look like aluminum (instead of a more gunmetal color) that would be great since radio signals can pass right through it.
My thoughts:
I'm not sure I would like the taper to be that extreme. Maybe a more slight taper is more realistic.
The rendering is not the greatest looking, but its not really meant to be an exact copy of what the iPhone 5 looks like, so cut them some slack. I would personally love a bigger screen, like 4+ inches. My best friend has a Samsung Infuse, (4.5") and it's not too big. It's much easier to type on and play games on. Why does everyone think they're too big?
I had a fourth-generation iPod touch (until I sold it to get my iPad) and the thinness of it seemed like a bad thing at first, but it actually started feeling thicker and more like a brick every day. It was extremely solid. I had a thin silicon case on it, and that made it feel thick as hell. Believe me, the thinness of the iPod touch is amazing!
Maybe this is the next iPod touch, but based on how much I used that in landscape for gaming, that extreme taper would not be too good. Again, a slight taper would be nice for aestetics (spelling?) and possibly a more even weight distribution. (Think how the first-generation iPad was exactly the same weight on each side in portrait.)
Just my two cents.
