That's about the same for any consumer grade bike hub, though, isn't
it?
Maybe. Down towards the Sora/2200 and basic Formula range, it's easy
to pit cones in a year. That said, spend ten bucks to recone them and
they're usually good for another ten years. Deore is finer in
comparison. As Muzi said. Shot of grease and a readust. Ride.

I was under the impression that Shimano cones were replaceable but
cups were not, not so?

Yes.

or do the cones generally wear out before the
cups?

Yes, for a couple of reasons. The cone surface is more highly curved
(and convex, not concave) and stationary in operation.

wanted to - I maybe only have 500 miles on it)

The real factor that determines repacking intervals is the amount of
rain you ride in and the quality of your seals. Good grease will last a
very long time if it doesn't get contaminated with water. My mountain
bikes are never ridden in the rain and I never repack them. I use boat
trailer bearing grease on my other bikes.

Under proper running with low contaminant ingress and keeping a
reasonable eye on re-lubrication, the cones should wear (very
slowly). When the cones have worn to an extent where replacement is
necessary (unusual) then the cups should be replaced if long service
is required as the original cups will be contaminated with hard
debris. If you want a cheap bearing to last, strip it when new and
wash out all the machining debris before re-lubricating with fresh,
clean lubricant. Any bits left in from the manufacture may cause
fatigue to the bearing surfaces and you will get pits.
