When you think of cyclists, you think of tight muscular bodies with sleek definition. It was the same thing with the Sony VAIO X505. This 1.9-pound beauty was constructed from a nickel-carbon composite most notably found in bikes, where it's used for lightweight durability. Bucking typical design trends, Sony placed the power button in one of the notebook’s circular hinges. Although the keyboard deck could have been placed higher up along the graphite-finished interior, the X505 was still a thing a beauty.
