Higher up front costs. A 4 pack of double or triple As only costs a few bucks, less than a dollar per cell even at retail prices. Comparatively you need to spend at least $10 just to get a couple eneloop cells, 2 to 3 dollars per cell, plus at least that much for a charger (a decent one is more like $40).
Then you have the hassle of keeping things charged, which realistically means having a stock of extra batteries lying around. Also, it doesn't help that the cheapest rechargeable batteries and chargers lead to a comparatively bad user experience (batteries not holding a charge long, low lifetimes).
Similarly, look at kitchen knives. Most folks have sub-par stamped kitchen knives instead of a decent chef's knife even though you can get decent ones for 30 to 40 bucks or so. It's a matter of high up front costs and not knowing what they're missing.
True, I always have charged spares and a high quality charger. Still, in the long run its cheaper, and better for the environment.
But then I also own high-quality kitchen knives and sharpen them regularly, cutting tomatoes with a blunt knive is something I refuse to do. Guess you're right.
