I have the older white MacBook with 1.83 Core Duo, 512 MB, and 60 GB HD. The HD only has 7.40 GB of free space left. So I figured getting a external HD for storing my photos on would free up a lot of space and maybe help speed it up. But what else can I do? Right now when I am running Firefox, Photoshop, iWeb, iTunes, and Mail it really slows down. I want to be able to run all these programs with out it running really slow and sticking when switching from one to the other. Thanks.
