We use ours once a day as a minimum, usually twice or three times a day. What do we do with it... I juice in it every morning, we make our own dairy free muesli, use it for sauces, rice, soups, chilli mussells, dips, pastry, salmon etc, etc, etc... That was a random list off the top of the head! We also churn our own butter (it takes minutes - do it!) make our own chocolate, crackers, bread, ice cream etc. The all-in-one meals are such time savers too!
You know exactly what is in your food, which is really important for us & for when bub comes along, it can (cant say will as it depends on how you use it) revolutionise your diet. And because its so easy to use, you can push the boundaries with your own cooking.
Just be warned, a lot of the recipes are straight out of the 80's and many are terribly bland (kid friendly maybe?) but there are some amazing cooks/chefs with their own Thermomix cook books who also do cooking classes with a Thermomix. Also, there are so many blogs & facebook pages dedicated to Thermomix cooking, you will never be short of ideas of what to cook. Enjoy.
