Magic Microwave Oven Combos

Sorry if this is silly, but I'm not understanding completely what these devices actually are.

I'm in the market for a toaster oven and I'm also in the market for a microwave. Most toaster ovens that I see are around 4000-15000 and microwaves are around 5000-20000. Then there is another group of devices which seems to start at around 5man and go up and over 10man. Are these microwaves and conventional ovens in one? I'd like to have convection but don't really care much about air frying.

What are these 10man+ devices actually doing?
