I bought EarthDesk v1.0 and then the paid upgrade to 3.0, and I like the program a lot ... but I cannot see why I would pay $10 to upgrade again to v4.0 ?

I like orthodox (2-panel) file-managers and was therefore happy to see that this program is being actively developed.

IMO the best file-managers can be driven completely from the keyboard. What Xfolders needs most is more keyboard shortcuts ... especially for the options in the Path Navigator contextual menu (e.g. to swap source/destination and 'Other Folder'). This applies equally to the favourites manager, where it doesn't seem to be possible to select favourites by the keyboard alone.

I suspect most of the potential users of this software don't want to use a mouse ...... ;) Look at the original Norton Commander to see what is possible.

Comparison to PathFinder is inappropriate in my view. With the dire state of the Finder, what Mac OS X needs is a fast, lean and mean application that confines itself to *managing files*. Xfolders could be that app if the user-interaction was made more efficient and intuitive.
