No harm at all.

Yes, but you do realize I am not asking how it works, but if there is any ill side effect to leaving it on all the time, right? Perhaps really bad gas mileage, or excessive wear us lesser mechanically inclined may not be aware of.

How's she goin' eh?
If you live in an area where there's tons of snow I would say yes. If your roads get dry I would say no. The system needs a little slippage, not a ton just a little to help prevent binding.

Any time you operate a piece of machinery it causes some wear and brings it closer to wearing out. You'll wear out your truck a lot faster if you drive 20,000 miles a year than if you drive 10,000 miles a year. The more time you spend in 4X4 the sooner you'll wear out parts.
Using it in 4X4 Auto won't really do any damage, but I'd not recommend using it all the time. Fuel mileage will be a little worse if you do although I doubt the difference will be huge.
But that isn't what the system was designed for. If the roads are completely covered in white stuff put it in 4X4 and go. With most 4X4's in areas where the white stuff is patchy I highly recommend 4X2 except where needed. The driver will need to be switching back and forth between 4X2 and 4X4 as road conditions change. The 4X4 Auto feature is meant for those patchy conditions where 4X4 is needed sometimes and not at others.
If the roads are clear, there is no reason to use it. But if you want to shift into 4X4 Auto and leave it that way till spring you can.

That's not how the 4x4A system works. It's designed for full time, all terrain, including dry pavement. The transfer case allows for slippage between the front and rear axle. The only penalty might be a very slight fuel mileage decrease.
