Cons unquestionably outweigh Pros: + Device weight (analogs in hardware are becoming heavier) + Design (thin and elegant) + Screen (bright, excellent color reproduction, light sensor present, but unable to function at native resolution) + A full day's worth of battery + Thunderbolt (the ability to connect tiny display port monitors and TVs to it, extending the number of other ports) + Filling (I have a version without a discrete ATI video card, although it is not generally needed) + Keyboard backlight + Reliable charger with extension cord + Bootcamp (second OS installation on Windows is unaffected by this feature) Cons are: Cost (nearly entirely justified) - Software (for Mac, there isn't much of it; in fact, it's a version of FreeBSD branded with a few settings; the OS itself lacks many of the features of contemporary Windows systems, but I haven't noticed any stability issues with the release of 7). - The absence of a full keyboard (the function keys should be used instead of the Numpad, Home, End, and Del keys, according to Apple). - ATI discrete graphics in the earlier model (Apple sacrifices performance and heat dissipation here to save money).
