Quick question: The memory slot in the iMac is.....darn small. I now have 12 gigs in it, the 2 original 2 gig chips and 2 of the 4 gig. I was looking at it wondering how the heck I would remove the original 2 gig chips to replace them with 4's when I go to 16. It's one thing to have tiny little fingers (I don't) but it looks like once you install the memory you're basically done forever. Ideas? The little tabs I only can pull so hard before they would tear it seems.
