and this other cool amplifier called an instrumentation amp :

So what does everyone else do?

Why do less that 1/4 of people use Java at all?
I have a suspicion that the earths population is around 3 billion. If I take that number and multiply it by the number of devices I have that run java I come to about 12 billion devices - so what are they using? Their lives must be bliss not having to wait for this to happen every fortnight.
