> There's no reason a 12" (and 13.3/14) laptop should be less powerful than a 15" or 17", though. yes there is. area and volume inside the chassis increase a lot faster than the length of the diagonal. the limiting factors for performance are heat dissipation and power. a bigger chassis can evacuate heat faster and house a larger battery that can sustain high power use for longer.
