My school is getting Macbooks. We are able to rent them out for the full year for $70. They are going to give us the cheapest 11 inch Macbook Air but we can pay for the extra 4gb of RAM. I multitask a lot, especially at school (photoshop or illustrator and chrome with music or a twitch stream playing) so I was thinking that the 8gb will be helpful. But since I don't want to spend the $100 if I don't have to I came here. I don't know how much RAM those programs really use but at school the computers have 8gb of RAM. They work fine but I don't know how much laptops need.
