The problem always mentioned is that you need lower temp and less time. The problem with the bread was that the temp was obviously not hot enough. But bread doesn;t cook well in warm air, it cooks better with a hot brick oven, therefore radiant heat source, not warm air. I think also it wasn;t able to heat the pot well enough. Maybe i just don;t have the experience with it, but i see no reason to try. I'll stick to it for simple things like cooking some casserole dish that doesn';t require the browning you can get from direct heat, and stick to my gas oven to cook with.
I guess one of the reasons i can;t get used to these ovens is that most of my dishes (roasts, etc) are cooked on the actual floor of the oven. I like teh heat to get directly onto the pan, so the bottom crusts. I use very high heat. I get really good results that way, nicely browned roasts and potatoes, for example, and cooking with hot air seems just one step beyond boiling. bla.
