(posted this in another thread but never got answered so making a thread for it) this might have been discussed in some other posts, so i apologize ahead, greatly appreciate it if someone can chime in: so i'm struggling with which model to get for the retina macbook pro. first of all, as some posters have pointed out, 2.3ghz and the 2.6ghz isn't a big difference in performance for most people. saw some benchmarks earlier and sort of backed it up. with 256GM of flash memory, i can live with it and just get an external drive to store all my non important files (there might even be a chance it can be an owc upgrade option in the future) but what i really want to ask is... 8GB or ram or 16GB of ram? do you think it will make a big difference in the next 1-2 years time? since the memory seems to be soldered into the board, i need to make the right decision before i go buy it... also, this is kind of random but, i'm currently in japan and for the people who might know this, will they have an option to pick up a US keyboard also and not only the japanese style keyboard layout (in store that is)? i read from somewhere it's possible but want to double check.
