    I could argue that 8 hrs is more than a full work day. Probably not a good idea to stare at a 400 nit screen for that long.

    I quite agree on both counts. I do not stare at a 400 nit screen with blue light waves blazing 1 ft. away - though sometimes 4k images and videos with the screen 2-3 ft away look too great to resist "flooring" the backlight and marveling at the nature photography and videography that's free for the asking on YouTube and elsewhere; hard to resist the indulgence at times :-D. Methinks I was both bragging and engaging in some hyperbole in response to a irritating comment about my allegedly poor choice of a device vis-a-vis its battery endurance. After struggling with the likes of Asus Vivo Tab Note 8 and Samsung Galaxy Tablet (2013) Note 8 for both viewing and inking there is such a gee-whiz feeling using this Samsung Chromebook Pro. I have little doubt that the Galaxy Tab S3 w/S pen and Super Amoled display would yield equivalent grins-per-page, but for $450 in a convertible form factor with a 12.3" screen and Wacom EMR it's hard not to feel giddy, despite real limitations on the kinds if "real work" you can do on the platform. Sometimes I just write in Squid or draw (well, doodle!) in Sketchbook for the pure fun of doing such gorgeous inking!

    Mate, I'm only holding you to your own standards: "with good (8 hrs) not great battery life".

    As for lightening up? You're being more unfriendly than I was. I have also been here a while (I just don't post much) and lurking for even longer. There's no need to belittle junior members.

    That's not really true.

    Windows 10 on Arm is an OS that is completely compiled for ARM processors.
    It only has an emulation mode for x86 software.
    So if you only use OS software and the UWP-Apps it doesn't need to use emulation.
    Even .NET SW will be running at full speed.

    If it needs to use emulation it is roughly as fast as an N3450 in Single Score geekbench and a 6y30 in multiscore.
    That is pretty fast for that battery live .

    Do you have a link for that? I believe you, I just haven't seen any article that does a detailed comparison.

    If you look at the scores that were posted for the devices like
    https://www.techspot.com/news/71895-leaked-windows-arm-benchmarks-show-laptops-failing-match.html and
    https://mspoweruser.com/first-leaked-benchmarks-windows-10-arm-alarming/
    you see that they have a single core score of ~1200 and Multiscore of ~4068.
    If you go to http://browser.geekbench.com/processor-benchmarks you see that singlescore is between the Z8750 and a N3450
    and the multiscore score of the 6y30 like http://browser.geekbench.com/geekbench3/search?utf8=✓&q=surface+pro+4+6y30
    is around there.
    The 835 gets 1904/6129 https://browser.geekbench.com/android_devices/350 so I would suspect that the native sw will run quite ok.
    Those numbers are compare in singlescore to a I3-4010U http://browser.geekbench.com/processors/1083 and the
    multi score is nearly at a I5-6300U http://browser.geekbench.com/processors/1712

    Thanks. If I'm understanding correctly those benchmarks are relevant for running software that is running natively, not running in some (partly) emulated form. So while the benchmarks look OK if somewhat slow single core, the actual performance running apps emulated might be even worse. Right?

    No.
    The score in https://www.techspot.com/news/71895-leaked-windows-arm-benchmarks-show-laptops-failing-match.html is the emulation score,
    because they used the normal X86 Geekbench for that.
    That's how fast emulated X86 software will be running.
    UWP-Apps will run native and there we roughly have the https://browser.geekbench.com/android_devices/350 performance.
