Pwnie Express has opened pre-orders on a Linux-based penetration testing device that supports 4G out-of-band SSH access. The Pwn Plug R2 runs the Kali Linux-based Pwnix distribution on a 1.2GHz Marvell Armada 370 SoC, and offers dual gigabit Ethernet ports, high-gain WiFi and Bluetooth, and a variety of one-click pen-testing tricks, like running the device as an Evil AP.
