The San Diego is based on Intel's Z2460 system-on-a-chip, which includes  a 1.6-GHz Atom engine in addition to a 400-MHz graphics chip. Thanks to  the Z2460's 32-nm process, it's power-efficient as well as zippy. The  San Diego boasts a 4-inch LCD display, in addition to an 8-megapixel  camera with 1080p HD video capture, a 1.3-megapixel front-facing camera,  1 GB of RAM, 16 GB of built-in storage space, and HSPA+ 3G, Wi-Fi,  Bluetooth, NFC, and HDMI.
The San Diego will ship with Android 2.3 Gingerbread, but Orange says  Android 4.0 is coming soon. Orange and Intel say the San Diego can surf  the Web for five hours and support eight hours of voice calls.
