What exactly is your argument here?

  I'm not the object of "your", but I might propose: Atoms have a higher power/computation ratio than ARMs. Atoms are attractive because you can run desktop/laptop software, but that is also a liability on battery. You are starting with a vast and possibly opaque codebase that was not designed for energy efficiency. I wonder though, as processors become more efficient and screens get bigger at what point does the backlight power dominate and the CPU efficiency become subordinate? A quick googling suggests laptop sized LED backlights are ~2 watts.

    Android offers pretty detailed power consumption statistics (as far as an operating system can tell, i guess). Currently it shows: Display - 46% Standby - 12% Handset inactive - 10% Android OS - 9% Android System - 8% Calls - 4% WLAN - 2% Rest is power consumption of apps.

      Which is why the new transflective screen technologies are a Really Big Deal (tm).

        That's why i am more curious about the Notionink Adam than about any other tablet. The display is said to consume only 10% and you can switch between full color and b/w "e-Ink" like display for easy reading. Sounds like the best of both worlds.

          Absolutely - they're using Pixel Qi technology. One that looks even more interesting (though not production-ready yet; they still have ghosting issues) is the electrowetting technology that Liquavista is working on. It would enable the "e-ink" like display in full color, full motion, with the power consumption of the black-and-white mode of Pixel Qi's screen.

  arm has a lower power draw, is cheaper to produce, smaller, and has a larger number of suppliers. Apple used the arm processor with good reason.

  That current Atom cores are not as power efficient as the ARM cores (and it's not just "by a little").
