Today my latest NewEgg order came. Nothing big, nothing fancy, just some RAM for my iMac. I found that IntelliJ, whilst an awesome IDE regularly consumes 600MB resident memory. Add to that 400MB for my Virtual Machine running Windows XP for testing, iTunes, Firefox eating around 600MB and Terminal that for some unknown reason has chewed through 120MB, not to mention mail, photoshop/illustrator and bridge, and my 2048MB was getting very strained. Also given that I had not rebooted in awhile apparently had a lot to do with it, but still, thats a high demand environment. I decided to upgarde my memory to 4Gig. Memory is cheap right now, and even Apple has instructions on their website on how to do it. There is a cute little slot at the bottom edge of the machine that holds the RAM. The only down-side is that it's only two slots of SODIMM RAM, which means only 4GB. If I could have I would have put in 8.
