I tried Upverter a few weeks back, and thought their UI made some wacky choices, particularly where sliding connected components is involved. Lack of hotkeys also was a big shortcoming in my mind.

Eagle and KiCAD are no picnic to start with, but they do at least have some features that allow you to speed up your schematic capture/board layout.

I've always wondered if there wasn't a business to be had in doing part creation for Eagle/KiCAD as a service...
