It doesn't seem like many computers figure out your average depth. Or is that because I've been looking in the low end range?

Most people don't think it's relevant, so it's not something they'll include.
Many comnputers do, but the download software does not use the data collected by the computer.
Somebody sells a thrid party program that uses the database information to figure out cool stuff like that. It would be really nice if I could remember the name of the software.

What possible use is it?
Plenty of people use average depth for gas planning, deco calculations, etc.Walter:
Some agencies even teach it these days.

Walter:
I've recently realized I'm fascinated by numbers and statistics. I thought I could figure my SAC more accurately.
jonnythan:
actually I believe only GUE teaches it per say, NAUI teaches RGBM in tech and some (AG) NAUI instructors add it but it is not a NAUI thing. But NAUI instrs are encouraged to go beyond standards.

Well, there are always 2 things you know after a dive, how long the dive was and how much gas you used.
If you add the third variable, the average depth, then you can extrapolate your SAC rate for that particular dive.
Over a period of time, if one has the inclination to do so, one can determine an average SAC rate for a certain type of dive.
Based upon those extrapolated rates, one can determine what size tank one would need to effect a given dive.

Suunto's dive software will use average depth to calculate your sac rate when you input the starting and ending gas pressures. A sensus data recorder will give you average depth for the dive, and also allow you to highlight a section of the dive and give you average depth for that section as well.
I don't know of any bottom timers offhand that give you average depth on the fly, it strikes a memory in my head, but I don't know for sure if it's because I thought it would be cool, or if I actually knew of one that did that at one point in time.
Computers will use your real profile to calculate the gas loading, as opposed to just max depth; but since your computer is doing the calculations for you, it would definitely wouldn't occur to the developers to tell you average depth, since it should be worthless to you since they will assume you have the computer to have it calculate your gas loading for you. [of course it's not worthless information to some of us]
