Microsoft, as it does for all platforms, has issued a set of requirements for Windows 8 tablets.

Microsoft does specifically address a "convertible" design, which is expected to become popular on both Intel- and ARM-based devices, CNET reports.

Convertible: "A convertible form factor is defined as a standalone device that combines the PC, display and rechargeable power source with a mechanically attached keyboard and pointing device in a single chassis.

Hardware buttons: Must have five hardware buttons. They are--power, rotation lock, Windows Key, volume up, volume down.

Broadband: And many of those designs will have built-in broadband. "If a mobile broadband device is integrated into a tablet or convertible system, then an assisted GPS radio is required," Microsoft stipulates.

Display: will have to be at least 1366x768 resolution. "

NFC: A visual mark is required for near field communications. "To help users locate and use the proximity technology, the use of a visual mark is required," according to Microsoft.

Alternative to Ctrl-Alt-Delete: The new option is to press Windows Key + Power.
