I have always thought it was quite easy to use, and very powerful. I suppose people are not putting together presentations on the Amiga much anymore, but it works great for an information terminal.
I don't think Commodore really marketed it much. IIRC, it only came with the A3000, not with the 1200 or 4000.
I was just looking at my disks last night, and I want to load it on my 4000 and see if it supports AGA or if I can use it with my Picasso II board. I doubt it, though...
