I traded my i5 8gb ram 2011 Mini for a i7 4gb 2011 11" MBA. I never paged out on the mini even when running photoshop and light room along with browsing. On my MBA I now page out up to 1GB-1.5GB but I wouldn't say that I notice it very much if at all. I think this is due to the SSD (samsung). I have no seen any beach balls yet. Does anyone else feel the same? I am contemplating on selling this MBA to get one with 8gb of ram and a 256gb ssd but mainly for the ssd since I realized 128gb is a little bit too small. Also, when I look at the graph on activity monitor, is it safe to assume that the blue area is basically equal to the green and can add them together to see my actual free space?
