I am currently using Lightroom on an iMac, but would like to go back to using a laptop for it. I have a 2012 11" MBA that I've filled up the SSD on so my options are either upgrading the SSD or upgrading the computer. I am leaning towards the upgrade of the SSD, but I'm not sure how Lightroom will perform on it since I have the model with only 4GB of RAM. It looks like that is within the system requirements that Adobe publishes, but I'm not sure if it will still run acceptably. Anyone have experience running it on one of these?
