I would like to know if the extra space is worth the money you pay for. I mean of course I would like to have as much space as possible, but it seems to me that once you pass the threshold of 512 GB prices ramp up exponentially. I am thinking of getting the MacBook Pro 15" with 512 GB or 1 TB. I don't make a living with the computer. I could use any other computer for what I am gonna use it for, but I like Apple computers. Actually; I already have a 2013 MacBook Pro 15" with 512 GB. I use it for web browsing, gaming on Windows, checking mail, keeping photos I take with my iPhone and using Office suite; basically Word and Excel. I am planning on selling after buying the new one. I already have an external HD; a Lacie one with 4 TB. At this point, I think I will buy the 512 GB version but my opinion switches back and forth easily on this issue. I would like to know other people opinions.
