I got a mac mini core solo a few days ago and I'm having a great time, but the system memory is VERY low. I've noticed especially that Firefox is a memory hog. What's a good web browsing alternative for this system (functionality vs memory use). Along side that however, upgrading memory in these systems is a pain, is it not? As I understand, it voids your warranty, is difficult to do, and even then, can I throw any kind of DDR ram in there or am I limited to certain apple ram (I'm a new switcher btw). Thanks for the help!
