Hello everyone. Apple is replacing my Air and I am wondering I should pay o upgrade the RAM, or if the store doesnt let me pay to upgrade the RAM I am wondering if the 4GB will be okay. Here is my usage: I am a homeschooled high-schooler and I use my laptop for web browsing, emailing, listening to music in iTunes, managing my photo library, in iPhoto (no photo editing of any kind, just importing and viewing and organizing). For school I write reports and stuff in Pages, take notes, and use the dictionary and calc for school. In addition to this I make YouTube videos in iMovie every two weeks or so, for my YouTube channel (nothing too professional, I have less than 150 subscribers). I also do the occasional home movie. Since I'm homeschooled, I won't be carrying it with me every day, and it will be used almost exclusively at home (however I dont need a desktop because I like using it in bed and around the house). Basically I want to know if I can get by with 4GB. I am currently using a 2013 i5, 4GB, 13' Air and it does fine; except sometimes with iMovie it stutters a bit. That is why I was thinking about 8GB. So....will I be fine with 4GB as I have now, or should I get the 8GB?
