heres an idea since youve already talked about the Raspberry Pi and have Sponsored Rev3 episodes that involved the RPi, how about building a 22 inch laptop using these minimum specs:
Monitor:
Asus VE228H 21.5-Inch Full-HD LED Monitor with Integrated Speakers
http://www.amazon.com/Asus-VE228H-21-5-Inch-Integrated-Speakers/dp/B00413PHDM/ref=sr_1_2?ie=UTF8&qid=1349558416&sr=8-2&keywords=Asus+ML228H+21.5%22+Full+HD+LCD+Monitor
Raspberry Pi board
Any form of linux (hopefully either mint or gnome will work)
at least 6-8 USB ports for attachments such as wifi dongle, external hard drives, wireless mouse, external burn/read disc drive etc
power supply with surface push button switch or toggle switch to power on the system
built in keyboard with direct line to raspberry pi or secondary (arduino or pcb board to interface with raspberry pi)
1 or 2 micro fans to make sure everything stays cool on the case
total thickness of case and monitor closed around 1 1/2 inches
lightweight materials
I hope this build gets done because i want to learn how to do it myself because i know only about half of what i need to do to build it
thanks for all you do Ben its good to see those out there inovating the world around us
