I assume some developer will use a new MBA at this time. Let say with XCode for some iOS development. Do you create a ram disk to write the temporary files during compiling to a ram disk or do you write them to SSD ? I wonder if with 4GB of ram it would make sense to make a 256MB ram disk for .o files etc. Since those are not needed on long run they could be stores in ram only avoiding too much write-stress on the SSD. What do you do ?
