OK, here is an answer.

Processor clocks are getting cheaper faster than memory is. Memory is getting cheaper faster than disk is. Disk is getting cheaper a *lot* faster than bits-per-second of bandwidth.
Memory is getting bigger a lot faster than it is getting faster. Disk is getting bigger a lot faster than it is getting faster. No matter at which part of a computer system you look, space increases more than speed does.
The "right" tradeoff is to use lots of cheap resources in order to be able to use fewer expensive resources. Therefore, as these trends continue,

I know my ADSL can download bzip2 files faster than I can decompress them...
