    I am by no means a kernel level Windows 8 expert, however, I think terms are being confused. WinRT is an API set for Windows 8 application development, which will replace Win32 if/when Microsoft jetisons the desktop. WinRT, just like Win32, sit just above the Windows 8 kernel.

    Windows 8 devices running on an x86/x64 architecture (tablets, laptops, desktops, etc.) can run apps built with the WinRT or Win32 APIs because both APIs can run on x86/x64 architected processors. Windows 8 devices running on an ARM or other SoC architecture will not be able to run Win32 applications because Microsoft decided not to port Win32 to support that architecture.

    The kernel will obviously be different for ARM and x86/x64 devices. The WinRT API, which talks to the kernel among other components, will be the same.

    I agree my experience in terms of performance on my tablet will be different than those with ARM tablets or even x64 tablets with different processor and memory configurations. I do believe, however, that my experience with the functionality of WinRT (Metro) apps will be identical.

    Windows 8 is Windows 8, whether on an ARM or x86/x64 device. I have the Win32 and WinRT APIs at my disposal. ARM folks just have the WinRT API.

    You are correct. I was using WinRT as shorthand for Windows RT, which is the ARM variant of the OS, which differs at kernel level from the x86 variant. Windows RT is so named because it will only run WinRT (Metro) apps and not desktop Win32 based apps.

    As far as a tablet goes, I will be going with the RT version. internet, games, entertainment, and reading is mostly what I will be using the tablet for. I will also get a pretty nice all-in-one desktop W8 for the office (at home). I do have a business laptop that I will not upgrade to W8 only because the IT people at work will have a fit. I've talked to the IT folks and it appears I know more about W8 than they do.

    x86 for me. I can't see Metro app selection being good at launch...

    but sluggish compared to Tegra 3.

    Tegra 3 is great. It competes fantastically within it's own power bracket and is massively competitive. It isn't, however, anywhere near as powerful as the majority of Atom chips. The recent benchmarks of that single-core Medfield chip hit that one home; they took a single Atom core, stripped it down and crippled it until it would fit within a Smartphone TDP. Despite this, it's still more powerful than most of the ARM SoCs on the market (barring the deficient GPU).

    Tegra 3 is massively more power efficient than current Atom chips, but those Atom chips are in a whole different world of computing power.

    RT stands for retweet.
