I've uttered the same sentiment myself (admittedly as an excuse for still running a 386sx in the mid-90's)

However this is only productive if you're not working with (a) compiled code, on a (b) project large enough that compile times are non-negligible

In some build environments, the difference in RAM or CPU is measurable in terms of (literally) hours of wasted time per day :(
