Gamers don't care about battery life (well they "wish"). And for gamers, the battery issue can be moot with dedicated video that is more power hungry too.
I agree you need to balance your objectives, but you can't force your view on all others. That's why there are choices to be made and why the P4-HT is available in a laptop. Yes the battery life is shorter, but it does work for those who can't do with less.
As an example, I have this C3 based mini-desktop that runs on well under 40 Watts of AC power. It's all of 733MHz but does fine for collecting weather data. But I wouldn't try a 3D game on it.

Correct me if I'm wrong.
Is Dothan by all means completely better then Banias?
In fact, I don't think so.
Banias runs at slower internal and external clock speed, less cache, etc. You may wonder how is it not completely worse then a Dothan?
If you have heard about why Pentium4 failed the beloved Pentium series you'll know it. Here is the primary reason: Dothan have more pipeline stages to increase clock speed. Pentium-M Banias have 10 while Dothan have 12. Pentium4 have more then 20 for those who don't know.
Now let's see about the pipeline stages cycles per second.
Banias 1.5GHz vs Dothan 1.6GHz.
Banias 1.5G: 1500/10 (mil) = 150M
Dothan 1.6G: 1600/12 (mil) = 133.33M
In theory, Intel attempted to overcome the decreased pipeline stages cycle rate by improving the organization instructions of the pipeline stage system. They did a decent job here, as you can see dispite of the fact that Dothan 1.6GHz have double L2 cache, 50% faster external clock, it is somewhat on par with (or worse then) Banias 1.5GHz in terms of performance. Mostly because of faster external clock means faster memory, but that was not the bottleneck really.
And Dothan eats more battery since it has way more transistors as well. Add in the fact that Banias have a few ULV(Ultra Low Voltage) models at the moment, which is just the best mobile solution around.
