Windows Phone 8 Detailed, Uses Windows 8 Kernel
MrSeb writes "Thanks to a leaked video — a video that Microsoft made for Nokia — we now have lots of details about Windows Phone 8 (WP8). From deep Windows 8, Skype, and SkyDrive integration, through to the addition of NFC 'wallet' payments and BitLocker encryption, it sounds like Windows Phone 8 will be close to iOS and Android in terms of features. The interesting stuff is under the hood, though: WP8 will have the Windows 8 kernel instead of the Windows CE kernel of its predecessors. Through the Win 8 kernel, WP8 will support native code and multi-core processors. It will also have the same network stack, security, and multimedia support as Windows 8. While Win 8 apps won't be directly compatible with Windows Phone 8, Windows Phone manager Joe Belfiore says developers will be able to 'reuse — by far — most of their code.'"
Not to be a dick, but your argument comes about half a decade late. Microsoft really did everything right in terms of security since XP. They minimized the damage that the biggest issue, user, can cause to the system, hardened the system itself significantly, slapped a properly functional firewall into a default installation and so on.
