Lexar JumpDrive M20 Mobile USB 3.0 Flash Drive

Lexar creates a Janus device that presents two faces to USB connectors

Many tablets and phones, these days support a standard called OTG or USB On-The-Go. It's a standard that allows a USB port to flip direction, allowing USB devices to work as if they were plugged into a PC. By inserting a flash drive you can augment what storage you device includes, and it's generally easier/faster to connect up a flash drive to the PC to transfer documents you can access later on the phone or tablet.

Devolo dLAN 1200+ Starter Kit

Devolo strains to make electrical house wiring match four twisted pairs of gigabit Ethernet

I've reviewed many Powerline networking adapters over the years, and of these Devolo's are some of the best. I like the simplicity of its designs, and how they normally work out of the box without any encouragement. Where I've taken exception to Powerline equipment in the past is when gigabit Ethernet ports are added into the equation, ignoring that the technology isn't capable of that speed (or even half that level).
