In June 2010, a smartbook device from Toshiba was announced. It features Nvidia Tegra 2 processor and is able to remain in stand-by mode for up to 7 days.[1][2] It has from 8 - 32 GB eMMC chip, some models have integrated bluetooth and 3G module.

The Device has considerable traction in the free and open source software community as it is possible to replace the pre-installed Android with a proper Linux system.[3]

The AC100 is the reference device for the Ubuntu ARM port.[4]

The AC100 was discontinued in 2011 and is no longer being manufactured.

  • embedded flash (type depends on the model, e.g. Toshiba THGBM2G7D4FBAI9)

  • Wifi (Ralink/MSI rt3070sta)
