Sony N505VE Review The N505VE maintains the first impression you get of the original 505 models. It's light and thin. Really. Upon removing it from the box, I noticed that it felt even lighter and thinner than my 505F. Checking the specs, it is, but just a little. It's likely that only a year of practice hefting the old model made me notice the missing ounces shaved from the N505. Added coolness factor: the magnesium lid is molded with the VAIO logo, whereas the older models are simply painted to look molded.
