For the 2GB MBA owners, with which OS do you have the best experience? How many apps have you running? I run currently Yosemite on my 2GB 2010 MBA, which is running ok, but is Mavericks or maybe even El Capitan better? Usually use Safari with some tabs open, Mail, Excel, iMessage, Dropbox, Photos and some occasional others. Just curious.
10.11 El Capitan is better than yosemite under every aspect!
I think the only faster os was snow leopard
