For the average, everyday user...it really doesn't matter. I think too many people are hung up on the "bigger is better" mentality, and feel the need to get a huge internal HD. I am only using about 45 out of 60 GB on my eMac and about 15 out of 40 GB on my iBook. I regulary clean out old files and junk that I have little to no need for. I would imagine that not all, but quite a few people could actually free up HD space if they did the same thing. Move those files to a CD/DVD backup and file it away.
So, if in the rare event that you might actually need that movie you haven't watched in two years, or that paper you wrote back in 10th grade, you can pull the backup CD out and put it back on the HD. :black:
