Slide 4 on the intro is wrong, Pong came out in the early 70's, in the 80's we had the Z80 and the Motorola 68000 in most of our arcade games. http://www.nand2tetris.org/lectures/PDF/lecture%2000%20introduction.pdf

bad example BMW will not sell you a brand new car if you are a Canadian resident :). this is a good read if you plan on importing a car. http://www.redflagdeals.com/forums/showthread.php?t=307601&highlight=Import CAD MSRP and US MSRP are like comparing apples to oranges. You really dont know what kind of savings you will have until you actually bargain with the US dealers. $20k on a Subaru Outback is a huge savings IMHO for a couple hours of work.
