More information on The Deck can be found here http://ppolstra.blogspot.com/2012/09/introducing-deck-complete-pentesting.html Please note that this website will not allow uploading the 3GB install file for The Deck. The appropriate images can be downloaded from my website listed on the blog or preloaded microSD cards are available from a vendor also listed on my blog (I don't get any money from the vendor, so don't feel like you have to use them, it is up to you to decide if you want to save the hassle).
The Deck works equally well on systems with a 7" ULCD7 touchscreen or with an external monitor/TV via the BeagleBoard-xM HDMI or S-video port. My personal setup consists of a BB-xM with the ULCD7 mounted in a Buzz Lightyear lunchbox, a second BB-xM without a display, and a BeagleBone. I connect them together with a USB-powered network hub. I also have 2 Alfa wifi adapters and a directional antenna for wifi hacking.
The Deck debuted at 44Con 2012 in London in September 2012. The slides from my 44Con presentation are available at http://www.slideshare.net/ppolstra1/polstra-44con2012 You may find these useful if you want to build one of these devices. You might check the website http://44con.com as the audio and video from this presentation may appear there. It was also presented two weeks later at GrrCON in Grand Rapids, Michigan so you might want to check http://grrcon.org for that video as well.
