The ubiquity of toaster ovens means that many people know recipes specifically designed for them. Bread, for example, cooks differently in microwave ovens. Most small convection ovens, however, can be used without the fan, allowing them to function like standard toaster ovens.
Convection generally allows food to cook faster, but it also keeps more of the moisture in the item being evaporated. Toaster ovens are simple devices that are cheaper than convection ovens, making them a smart purchase for people who prefer standard toasting. Traditional toaster ovens are also generally smaller than convection ovens, which allows people to conserve space in the kitchen.
