Yeah, I know, I discovered that yesterday and fixed the link. They had gotten corrupted. (If you want to try again it should work now.)
You bring up an excellent point for others still waiting - there’s a learning curve on every new tool.
This one is actually pretty short, but unless you are buying all of your designs pre-made, it ain’t no Cricut. 
The design process is what folks can start to get familiar with before they get their machines, and speed up the learning process somewhat. (That’s why all the tutorials are there. We tried to find links to vids or write up little “How-Tos” for as many of the 2D vector and 3D modeling programs as we could. In addition the little “Getting Started” tutorial listed below does an overview of How to Design for the Glowforge Laser, and there’s a whole section for it in the Matrix )
