10.1" HDMI Screen with attached keyboard and touchpad! (Motorola Lapdock 100) for $49.99 + free shipping
Yeah, yeah. It's a smartphone lapdock. Me, I like to think a bit more outside the box though. Looking a bit more closely, this is a small HDMI screen and a USB keyboard/mouse!
Imagine an additional (albeit small) computer screen - perhaps one to watch Netflix/Hulu/etc? Imagine the possibilities when you add a Raspberry Pi, Android Mini PC, or other device that requires only power, HDMI, and USB? (Many of which are under $50.) The possibilities are literally 3+!
