I just got my rMBP a couple days ago and love it. I got the upgraded 2.6 and 16ram. However I only got 256 hardrive. I only used about 80gb on my old PC. But now that I have MAC I am so tempted with all the apps which of course take up more space and am now regretting getting 256. I don't download music and will not be downloading that many movies. I do however have many pictures and use up approx 30GB per yr for software files. I do like to upgrade to a new computer every year but I had planned on keeping this computer for 2 years. How many of you upgraded to 512? I know its a big no no, but if I found someone, is it possible to upgrade to 512 later? Apple genius told me apple won't do it bc its soldered in.
