Hi I've bought myself a mac mini 2,3 i7 (4GB ram, 1TB HDD, no ssd) to program for ipad/iphone. I am following the Stanford itunes course. I had to type 8 lines into a simple Attributor app (as in week 5 of the itunes Stanford course) and everything went sluggish. On compiling and launching the simulator I lost about 5 minutes. Which upgrade is recommended? Will plugging in 16GB ram do the trick? Tx for your answer !
