              Recently the hardware requirements for PC and Devices has been published. In last December, Microsoft had published a Hardware Requirement Documentation for Windows Logo Certification. Here are some interesting Hardware Requirements For Windows 8. 

* 5 Point Digitizers. 
    Microsoft states that touch screen with minimum 5 touch points are required if you are a user of Windows 8 Touch Screen PC. But the funny fact is even the latest HP TouchSmart has only Two Touch Points. 

* NFC Touch Marks
    Microsoft requires that Windows 8 PCs featuring NFC technology have “touch marks”. This one is a no brainer – A PC, likely a tablet or slate, must have a sticker or similar signage indicating where another NFC capable device can mate with it.But we’re not used to NFC being visible in this manner.

* Hardware Buttons
   Microsoft also says that the tablets would have to gain 5 Hardware buttons for running on Windows 8 (Not 3 or 6). Those Buttons Are
*Power
*Rotation lock
*Windows Key
*Volume up
*Volume down

* Combo Button For Ctrl+Alt+Del
    Tablets must have an combo button for Ctrl+Alt+Del if its on windows 8. While the on-screen keyboard remains an option for logging into a domain-joined PC, the quicker (and new) option is to press Windows Key + Power.
 
* Component Sets For Windows 8
    Microsoft 8 also requires some minimum component sets for windows 8 tablets / Convertible PCs (Not Minimum Actually)

*  Storage: At least 10GB free space after the out-of-box experience completes
*  System firmware: UEFI
*  Networking: WLAN and Bluetooth 4.0 + LE (low energy)
*  Graphics: Direct3D 10 device w/ WDDM 1.2 driver
*  Resolution: 1366×768
*  Touch support: At least 5 touch points, must pass all tests
*  Camera: 720p
*  Ambient Light Sensor: 1-30k lux capable w/ dynamic range of 5-60K
*  Magnetometer
*  Accelerometer: 3 axes w/ data rates >= 50Hz
*  Gyroscope
*  USB 2.0: At least one controller and exposed port
*  Speakers

* No Reboot Driver Upgrades
     These requirements are sometimes funny right ? As a part of it, Windows 8 PCs will not support reboot upgrade of graphic card drivers. Finally. While Windows Vista has supported reboot-less upgrades of WDDM drivers, enforcing that requirement was hard with unified driver sets containing both XDDM and WDDM drivers mixed in. With XDDM drivers gone in Windows 8, however, enforcement is easy and should be welcomed by users and gaming enthusiasts with wide open arms.

* 2 Second Resumes
        Microsoft doesn't require that Windows 8 ARM PCs resume in two seconds or less … only Intel-compatible Windows 8 PCs have this requirement. And yes, the two seconds max for Standby (S3) to “resume complete” requirement was in place since Windows 7. But I suspect ARM doesn't come with this requirement because of architecture implementation volatility or, more likely, that Microsoft simply doesn't yet have enough data in this space.

Lets see will those interesting hardware requirements may used as a criteria for Windows 8 support (I Dont think i am gonna get a windows8 tablet/PC soon)
