What about under-cabinet lighting? While I think the extended cabinet lip would make it very easy to moun virtually any light source as task lighting, I usually mount outlets above the counter backsplash (in the wall itself) to avoid hassles with potential remodeling of cabinetry (?) in the future. Making the required small appliance wiring a part of the "removable" cabinets asks for difficulties down the road, IMHO.
Also, when receptacles are hidden from direct view it's more difficult to insert plugs, and I would think it would be more tempting for H/O's to do the "grab and jerk" on the appliance cords rather than grasping the plug body itself.
