Apple has encouraged us to use our Macs as the hub of our digital lifestyle. Having done that--used my desktop iMac as a repository for almost 12,000 iTunes songs, almost 19,000 photographs (most of them in relatively high resolution), a handful of iMovie videos--I find that the 233-odd gigabytes of my hard drive are now just about full. Though I probably have more applications than most would have loaded on my Mac, the bulk of the clutter is digital musical, photographic, and video content. This means I need to do some pruning: dumping those out-of-focus pictures from iPhoto, converting MP3s recorded at 320 or 192 kbps to 128 kbps AAC files, and storing old video data in one of my two external storage drives.
