I can get 8 AA and 4 AAA eneloops WITH a charger for $20. I think NP-400
withOUT a charger is at least $20.
Actually, they are $9.95 from B&H:

$4.95 for shipping; of course, you can get two or three for the same
shipping charge. And the charger, of course is not needed, because it
comes with the camrea.
Ok. So, $14.90 for one NP-400. $24.85 for two NP-400.
For $20, I get 8 (8 = eight) AA and 4 (4 = four) AAA Eneloops. With 8 AAs that's like having two NP-400s since *ist D/DS/DL/K100D uses 4 AAs at a time. ALSO, I get 4 AAAs. I use the 4 AAAs to power my Flashwaves (two of them). Also, once the AA's get depleted to be unable to power my ist D, I can still use them on my flashes.
Let's spell V E R S A T I L I T Y.
When I used K10D, I don't remember the NP-400s lasting much more than my AA Eneloops. I've not done any controlled testing to be certain, but after using both my K10D and ist D for about a year each, that's my impression.
I'm with Richard: I love the single-battery approach. The single
battery was one of many things I liked much better about the K10D
over my ist DL.
I understand the advantage of single proprietary lithium battery approach. I understand that it provides more juice. Perhaps with CMOS sensors, AAs may be sufficient.
Again, while there is an advantage to proprietary lithium battery, I don't see much advantage as a consumer for that approach. Perhaps it's necessary for faster professional grade DSLRs. But if K200D with CCD sensor can be powered with AAs, I wonder why K20D with CMOS sensor cannot use AAs.
If (1) Pentax sticks with just one model of proprietary battery that can be used from one generation to the next generation of its cameras and (2) the price of such batteries remains as low as $9.95, then I'd be less reluctant about it.
But, at least for now, after having used both NP-400 and AAs, I prefer AAs.
I have never found a decent set of AAs in a gas station; the last set
of alkalines I bought for my ist DL lasted about 20 shots.
Well, at a gas station, you can get alkaline AAs made by such companies as Energizer or Duracel. As AAs go, those are quite good.
And, yes ... the alkaline AAs don't last very long in DSLRs. But 20 shots is much better than 0.
I would NEVER go on an important photo trip like a safari with any
hope whatsoever of finding decent enough AAs to get me through the
trip. Even if I found any, I'd have to buy 30 or 40 sets.
Have you ever been on a long trip? So, let's take your silly hypothetical. What is your plan then? Lug around 3~5 NP-400s and the charger? For my ist D, I'd just take several lithium AAs. They last longer than NP-400 did in my K10D. Also, I can toss those lithium AAs to lighten my load as I travel. For some reason, if my lithium AAs all run out, I'm sure the chances of finding even alkaline AAs for 20 shots would be pretty good.
Now, what's the chance of you finding an electrical outlet? I guess you'll also have to carry plug adapters.
Another advantage of AAs. As mentioned before, used AAs that are no longer good enough for my DLSR is still good for my flashes. It's rather like killing 2 birds with 1 stone.
It seems somewhat silly to even pose this scenario. Would anyone plan
for such an important trip without considering batteries? And if they
did, there's a good chance they forgot a telephoto lens, too...
Well, unless you travel like a king with a caravan following you around, for many travelers, there's the dilemma of limited space in bags.
Exactly as you pointed out, because when people plan for important trips, they consider batteries, AA is better.
In my particular travel through Europe for 30 days, I had to pack everything in my backpack. So, space was premium. If I were to travel through Asia, e.g., Japan, Korea, China, Vietnam, etc., with AAs, packing decision would be simpler because I know that AAs are available everywhere. With a proprietary battery, I'd have to worry about carrying not only the charger, but also adapters for the electrical outlets.
Also, consider this. Even in some of those countries where electricity supply is a bit spotty, you'll have a good chance of finding AA batteries.
So, why don't you actually try planning such a trip? See what you end up packing. Instead of just trying to do things on a paper or in your head, actually take out your travel bags and start packing them. See if they all fit as you think. See what you end up leaving out. Then see whether it'll be better to have a camera powered by AAs or by proprietary rechargeable battery.
I speak from actual experience of having traveled with both types of cameras and actually having used both ist D and K10D.
