OK, I'm sitting here with two Vitamix blenders. The 750 and the 300. One is going back! I admit I mainly wanted the 750 for it's looks, but I at least hoped I would also find the presets useful. On it's looks, I also don't find the presets lighting up in pale lilac that attractive next to the stainless finish. Blue would have been cooler! The presets seem to be just time set programs more than being adapted to the temperature and ingredients in the container. For instance the soup preset will run for 7 minutes whether you need that long or not. Starting with hot liquid will overcook your soup using 7 minutes until it shuts off. The smoothie is also a set time whether you need to process that long or not. It runs longer in case you have harder to blend veggies in your smoothie. It's basically covering it's rear :-). Just as easy to stop it when you don't see any pieces spinning around. The puree I don't find useful as you want different textures for different recipes. The frozen dessert preset still needs you to stand there with a tamper. I find I don't need all that time on the cleaning preset to get the container clean.
For those who have the 750 in what way do you find the presets useful? Am I missing something in not loving those presets? I wanted to get some feedback before returning it.
