I was looking into getting a 14-inch ibook soon. Im torn between the 1 gHz 768mb ram and the 1.2 gHz 256ram (which i would add 512mb later on my own). They would cost about the same if i got my 512 stick from crucial and installed it myself. How is installing extra memory on the ibook? Is it relatively easy? Should i go for the 1.2 or get the 1gHz (which I would not tamper with)? Any advice would be appreciated. Thanks.
