• Intel® Insider™ is a hardware-based content protection mechanism. Requires a 2nd generation Intel® Core™ processor-based PC with built-in visuals enabled, an Internet
connection, and content purchase or rental from qualified providers. Consult your PC manufacturer. For more information, visit www.intel.com/go/intelinsider.
• Security features enabled by Intel® AMT require an enabled chipset, network hardware and software and a corporate network connection. Intel AMT may not be
available or certain capabilities may be limited over a host OS-based VPN or when connecting wirelessly, on battery power, sleeping, hibernating or powered off. Setup
requires configuration and may require scripting with the management console or further integration into existing security frameworks, and modifications or
implementation of new business processes. For more information, see http://www.intel.com/technology/manage/iamt.
• No system can provide absolute security under all conditions. Requires an enabled chipset, BIOS, firmware and software and a subscription with a capable Service
Provider. Consult your system manufacturer and Service Provider for availability and functionality. Intel assumes no liability for lost or stolen data and/or systems or
any other damages resulting thereof. For more information, visit http://www.intel.com/go/anti-theft

Most Android* Apps Will “Just Work” on Atom
Android Dalvik apps
• These should “just work”– we do extensive testing of
pre-production systems
Android native (NDK) apps
• Most will run w/o any recompilation but …
• A simple recompile using the Android NDK yields the best performance
• If the developer uses ARM-specific features, add equivalent Intel SSE features
Top Android Market apps

“Thanks to contributions to AOSP from
Intel, the emulator now supports
running x86 system images in
virtualization mode on Windows and Mac
OSX. This allows the emulator running at
near native speed.”
