Microsoft is resurrecting an old idea, the “SideShow”.  For those of you who don’t remember it, it’s a small display set up near your main display for showing other context data.  Now touted with touchscreen capabilities and such, they’re retargeting it at gamers for use as an additional data display for in-game maps, health, inventory, etc.

With devices like the Intuos offering something similar (albeit with alot of extra nicer features), and things like Mimo Monitors connected via USB, is the time finally right for this?  Or just another unnecessary gadget?

Microsoft SideShow could offer gamers secondary touchscreen – SlashGear.
