I know it's only £80 but if I can save that money great. I'm coming from a 2006 iMac and 2007 Macbook. I use Illustrator/InDesign daily for my job, light photoshop, even less video. If it's about 4gb being sufficient for now but not in 2-3 years wouldn't it make sense to upgrade to a new machine in 2-3 years which will have new processors/display/battery life?
