Although it's pretty easy to hook up a Raspberry Pi to a screen using its HDMI port, it's not exactly the most portable of solutions (especially if there isn't a TV or monitor around). The Raspberry Pi Foundation recognized this, so it set about finding a "simple, embeddable display" capable of giving Pi owners a screen from which to work from, but that also embodies the DIY spirit of the board that it connects to. It's taken almost a year, but the official Raspberry Pi touch display has gone on sale today, offering tinkerers a 7-inch capacitive 800 x 480 touchscreen display that supports 10-finger touch.
