the problem is that when you freeze things the ice crystals break down the cell wall, hence the "mush". This also happens when you cook things. So frozen fruit that is destined to be cooked or pureed(ie baked in a pie, blueberries added to pancakes, made into a sauce, or pureed into baby food) is GREAT. But if you want to eat it like, well, a piece of fruit... stick with fresh.
