I finished it a couple of months ago. It uses the exact same structure and software as described in the book (HACK language, etc).
The included hands-on projects made it more fun and interesting. Basically you'll build a simple computer from the ground up, starting with flip-flops and going all the up up to ALU, memory and CPU.
The grader works well, so you can submit your code and it'll grade you in realtime. You can finish it in less than a month, if you have experience with electronics and Boolean logic.
I've gone through the book and got as far as building the computer, writing the assembler and running some programs on it. Does the course go beyond this? I haven't built the virtual machine or written the compiler, but it looked like from the description of the course, they didn't do that either.
According to the Nand2Tetris site[0], this is just part 1 and only covers chapters 1-6. Part 2 will cover chapters 7-12 but looks to be still in development.
