I'm nearly tempted to round up some new friends for one lol. I reckon a third one would be handy.....lazy much?
I think some people multiple bowls just suits their style, I tend to get a burst of TMX cooking done all at once, so a second bowl very handy - once I get started I just want to make loads, but sometimes it can go a week unused. I still think they should do a 'bulk' cookbook where they line up the recipes so don't have to rinse and/or clean in between. Often I think if only had done that one first.
