If you're shooting landscapes, I'd be surprised if you are using anything like wide open apertures or need fast shutter speeds, therefore I see no need for a fast lens. I see more need for a good dynamic range and low noise, which you are more likely to get from a bigger sensor.
For your portrait work, I can see that a fast lens may be advantageous if you're using available light, but you really should be thinking about the effects of using wide open apertures on the DoF. You may be able to bump up the shutter speed to avoid camera shake with a fast lens, but do you really want a minuscule DoF for the given subject?

No. Compacts particularly are poor in terms of noise.
