Hey guys, i'm looking at buying a new 15".4" macbook pro but the only issue i have is the harddrive space.
On B&H there is almost a $400 price difference between the 2 that i am looking at and the only difference is the processor speed(2.3 vs 2.6) and the harddrive space (256 vs 512).
is there any way of gaining more harddrive space without paying an extra $400? i'm hoping not to use externals but i think i might have to.
