I see a lot of threads/posts where people are getting 8 GB, or are unsure if they should get 16 GB. Trust me, those are the same people who will be starting threads in 3 years wondering what they can do to speed up their computer and the answer will be nothing since the RAM is soldered to the logic board. I'm surprised to see people say "For your uses 8 GB is enough". History has shown that that never proves to be true as the computer ages, proof being in all the threads where someone asks how to speed up their computer as it's become slow and everyone says upgrade the RAM. Trust me, get the 16 GB now and be done with it, then by the time software gets hungry enough to eat your 16 GB of RAM the computer will probably be 5+ years old and due for a replacement anyway. The last thing you want to do is have a 2-3 year old beachball paperweight because of RAM you can't upgrade because you didn't want to part with $200, which isn't much spread out over the life of the computer. Not to mention you could get 8 GB 4 years ago, so it's time to bump that. Really for the basic user 4 GB should theoretically be enough, but I don't see many people suggesting a 4 GB purchase. Same should apply to 8 GB, it should be enough but reality over time shows it won't be and there will be page outs doing basic tasks. I know my mid-2010 with 4 GB gave me page outs doing fairly basic tasks on a clean install of Mountain Lion, I wouldn't expect today's MBP to be any different X years down the line with 8 GB. You can never, ever have too much RAM, so you should *always* max it out.
