No, not goodbye iPad, not with Atom under the hood. An ARM slate running Android might be able to do it, though.

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").
