On one hand FP lets you program without thinking too hard about the numerical properties of your program - until you hit a gotcha. On the other hand FP is pretty powerful for many domains if you're a FP wizard. Like physics simulation. There have been other approaches besides fixed that people have tried out, such as interval arithmetic and exact (rational) arithmetic, but they all have their own problems.
