I feel being able to measure mA is a big part in building/troubleshooting digital circuits. Any thoughts?
I find I very rarely use the current ranges on my meters.
I don't often use the meter for measuring currents in digital circuits, because it tends to be "intrusive" and a bit of a pain to set up (I should create some fixtures where to make it easier to insert it into standard power supplies.) (like, use a meter to measure the current your arduino is drawing via the USB cable? painful!)
On the other hand, I have one of those "lab style" power supplies that has meters and limits for both current and voltage, and I *really* like being able to see (and limit) the current there...
