Rumor has it that Dell is planning its own dual-screen ARM-driven device, powered by a Qualcomm Snapdragon chip, similar to the piece of hardware Microsoft allegedly has in development.

We’ve been hearing rumors for a while now that Microsoft may resurrect the Courier dual-screen device abandoned many moons ago, and according to a source cited by WinFuture, Dell has been working on a similar dual-screen project codenamed ‘Januss’ (the name of a God with two faces, which makes sense – although it’s normally spelt with only one ‘s’).
