Hey guys, My first time posting. I'm about to order a Macbook Pro and I'm undecided between a regular 500gb 7200rpm HHD or the 128 SSD. I've heard the SSD is fast but I'm afraid it might not be enough space. Typically, hard drives actually have a little less free space than the number it indicates. For example, a 500gb might have about 460gb of free space. My question is, for the 128gb SSD, how much actual free space is available? Thanks in advance.
