There's a horrible rule with layout (and capture) software: The more power you want, the harder it is to use :)
If you want support for 36+ layers, multi gigahertz routing, advanced autorouting, spice integration and all the other bells and whistles of high end solutions, then the simple fact of it being so configurable is going to make it hard (initially) to use.
Even Allegro Expert can be simple - once it is set up. Get the board up, position the cursor, Shift+F1 and start drawing a trace. I will admit it takes days to set up a new board though, once everything is done.
So the answer to your question is: If you have a simple board, yes it's difficult; but vendors don't see much money in the low end. As noted elsewhere in the thread, there are plenty of free- and share-ware solutions if you just have a simple board to do.
