I bought my Vitamix 6 months ago and I have no regrets. The smoothies can be as thick or a thin as you want depending on the ratio of liquid to solid you use. I notice that the smoothies have froth on top when I use protein powder but that isn't the case when I use just fruit, veggies and water.
I have made the potato soup which came out hot and creamy. I haven't ventured into other soups but I would assume that the soup you made tasted like grass due to the ingredients you used. I use my Vitamix to chop up cabbage, carrots, and zuchinnis and other veggies into pasta sauce.
I love my Vitamix since it makes it easy for my to get my servings of fruit and vegetables. I don't like a lot of vegetables so the Vitamix makes it easy for me to sneak them into my diet without tasting them.
