i read somewhere that the pro line was meant for the pro-sumer. i have no idea what that means but i THINK it has something to do with wanting the best or top performance you can get for work and play. apples pro line has some interesting caps. first off, they dont use any quad core setups. 2nd, they underclock their video cards and dont offer up much choice in regards to graphic acceleration. apple has pieced together a decent machine with the 15"/17" for its power to battery life ratio however the pro-sumer cares not for battery life! he knows better than to expect that 4 cores will be kind to his battery. powerful chips need just that, power! he knows a machine capable of running crysis isnt running it for long without a cable plugged into a wall. he knows these things and he accepts them. for him the laptop is not a laptop. it is a portable desktop. a desktop replacement. whats my point? my point is apple could afford to be more pro. yes some guys want 30 min battery life but top notch parts/performance. you may not understand the want and you may not understand those guys but those guys do not wish to be understood. the solution? wider BTO options. who knows. maybe the market isnt big enough but thats why its called BTO.
