Sure, you can use a square or circular random orbit palm sander to get up to those edges, but you're either not getting right up the adjacent face of the joint, or you're leaving tell-tale scratches on the adjacent face from the side of your sander. I primarily construct cabinets and furniture, and I've found this tool to be extremely useful, especially in situations where I've got glue squeeze-out residue from, for instance, dadoed shelves, dividers, and cabinet box inside-corner joints. With the Bosch tool, that problem is non-existent, since only the edge of the sandpaper is contacting the corner joint. The sander is surprisingly powerful for it's small size, and the true random-orbit action makes quick work of sanding out even the tightest corners.
