Easy and tasty. Quick to make compared to many soups. Also inexpensive compared to many dishes. I would suggest, though, that if you want things healthy, you could leave out the cream cheese. If the potatoes and leeks are cooked properly (definitely sautee the leeks longer than 5 minutes, with a bit more oil), even just them blended with the water is quite smooth and tasty. A nice pick-me-up for a cold day.
