Looking to buy a 13" MBPr. I will certainly go for the 256Gb SSD but am still in doubt as to the memory. It comes with 8Gb as standard. My usage will not include pro apps, although I will use iMovie sporadically, as well as some light Indesign-Illustrator-Photoshop work. On Apple's site, it says multitasking is no problem at all with 8Gb, but if you're going to be using apps like FCP, it is advisable to go for 16Gb as this can not be upgraded later on. So, taking my usage into account, and considering I would like to continue using it for the next 4 years, will I regret going for only 8Gb ? I live in Belgium, so it's in euro over here. An extra 8Gb would set me back 240 euro, which amounts to about 270 dollars.
