You sound like someone who wouldn't be happy with anything Apple did. "If only they" is a slippery slope. If Apple went with 380 how would that solve your problem when you are claiming 200GB per semester? GD troll.If Apple Computers didn't mean anything to me, to be frank, i just simply wouldn't give a ****. 256 Gigabytes requires to have external storage to survive in a system that is not upgradable. If they had 320 Gigabytes I'd probably happy with it but 256 is not enough, it's just too close to what you need nowadays.
Or go for 380 I dunno but 256 is just too close to what you'd saturate nowdays.
They've played the same game with 128 and keep doing it with 256 until it is totally unexceptable.
