Shameless self promotion. From me, following my one year exile from Mac360: What Good Is The Desktop On Your Mac? Not Much.
The Mac’s Desktop metaphor is a relic from the golden age of personal computing; back when you needed plenty of money to buy an Apple product. The graphic utility of the Desktop has come and gone. The true benefit of the Desktop is nothing more than a folder to save what hasn’t been put away yet.
There’s also a proposed solution.
Flick the mouse pointer to a screen corner hot spot, as you do for Widgets, and whatever is stored in your Mac’s Desktop folder magically appears on the whole screen. You’d be able to open folders and documents the way you do in the Finder but without the Finder.
This would be a good area for some Apple innovation.
