I've got a white proto board I'll use a few times a year, more in the past. It's got a ~4"X6" panel attached with pots, switches, BNC's... I guess I like live bugs now because the piece of copper clad is somewhat more permanent and I'll often pull the circuit off the shelf and use it again... maybe to check a production board, or something new.
My white proto board only lasts till the next circuit. (I repurpose live bugs too...)
