From the little info they have on their website, the 'easy' version is a DNC program. Which sends programs directly to the machine. For the home user, I don't see much use for this, since most probably don't have an actual connection between their programming pc and their machine pc. But I'm sure some can find it usefull.
But it also seems to include an "organization" feature, which can centrally store and keep track of your programs. And also tool offset tables, if I read it correctly. Also an editor. Most NC specific editors have special functions that allow you to do certains things. They may include renumbering an entire program, search to 'next tool'/'previous tool', go to lowest/highest axis position, etc.
I haven't downloaded the trial yet, but plan to do so later this afternoon.
