Yes, a 32mb cache.
A 2TB HDD is just the next step up. You guys are all assuming that media will stay the same quality. As the common camera takes higher resolution shots, and as musicians start releasing more of their stuff in hi-def wavs (not commonplace yet, but it will be) instead of 128kbps mp3, suddenly it will take a lot more storage to hold your collection. My copy of NIN's the Slip in 128kbps mp3 is only around 50mb. My hi-def wav copy is over 1.5gb. Suddenly 2TB isn't so huge. A decade after, we'll be scratching our heads at such a silly question, wondering how one could ever do with less than a 320TB HDD, and maybe two if you had a serious music/movie collection.
