On the top edge are waterproof covers for both the micro-USB port and micro-SIM card, while the headphone socket, located between the two, is left open to the elements.
On the bottom, there's a standard tripod socket, an SD card slot and a battery compartment, complete with an 875mAh LP-E12 cell (replacements should run you about 75 bucks).
Somehow, though, MSI squeezed in an Ethernet jack and full-sized HDMI socket, along with two USB 3.0 connections, an audio port and a memory card reader, tucked around back.
