i am wondering if anyone tried running anything newer than Lion on 11" MBA (2010 C2D model) with 2GB of RAM. i am thinking of upgrading the computer from Lion. i was worried going from Snow Leopard to Lion that it would slow down but thankfully the SSD makes up for little RAM it has. from my understanding Mountain Lion uses probably the same resources as Lion so I guess I should be good to go. the computer is my girlfriend's and she's a light user (usually only browser and Mail is open, Adium and Time Machine running in background). any opinions?
