hey guys, i am soon buying a 15" macbook pro and i am in quite a predicament for a few reasons... SSD: the first being the price of the ssd for the low amount of storage. My concern is that this wont be enough and i dont feel like doing lots of other things like external hard drives and other inconvenient things. If i were to get a 128 gb for $90 bucks or the 256 gb for $400. but neither is very much memory for lots of money But the goods of ssd's is obviously there speed, no moving parts! HDD: These things are cheap and come with lots of storage. But the down side is they have have moving parts and are less durable also are slower.if i get one of these its free. I would choose the 500gb 7200 rpm. is it worth less memory and more money for better performance or should i take the free memory that isnt as powerful? So what do you guys recommend and think i should get?
