I agree with you on the ease of use. I used the program from the beginning, when it was called Drafix and before it was sold to AutoCAD. I teach lighting design at a college and have used it for years to teach students the basics of CAD. Simple and effective for basic drafting needs.
However, I have had to purchase and learn Vectorworks as most of the entertainment industry (lighting anyway) has gone that direction. I bought the Educational version of AutoCAD LT just so I could translate dwg files that were newer than 2007, but it is hateful! I just wish that Autodesk would support the program. I ran it on Win 7 for a while but it started acting up (not able to save files) so I now run it in XP when I need it. But now I'm Vectorworks (though it takes much longer to do a drawing in VWX than in AutoSketch).
I hope it comes back though. Hard to encourage new graduates to buy a program that will cost them $2500 when they could do what they need for a 10th of the price!
