The Bone is currently among my favorites, if not the favorite. I second your recommendation. I liked the Globalscale Sheeva/Guru/Dream for a while but their terrible build quality and ever changing spec put me off them quickly.
When I need graphics (mostly we drive plasma displays for signage) I usually use a Lanner. (http://www.lannerinc.com/Embedded_Computing) Fanless, cooled through aluminum case, generally indestructible and less than $300 each in bulk.
If you just want to throw a switch via wifi, a TP-link 703N with OpenWRT can do it for you for even less than the cost of a RasPi. I've got one opening my garage door from my iPhone.
