A regular distance/speed computer is kind of nifty to have, but shouldn't be used to guide your training. HRMs and powermeters are just ways of quantifying effort level. But you can measure effort level the old fashion way ("doesn't hurt", "hurts a bit", "hurting now", "hurting lots").
i think numbers can make you go harder. for training, until you get used to spinning, a cadence meter is really handy.
i find that my preceived exertion depends on my mood, whereas HR will tell me my body's actual effort
a method of keeping track of time is very important for training
