It is always good to have a compact point and shoot camera, this is something I'm missing now. So I don't think buying a compact for your wife now would be a bad thing to do even is she picks up a DSLR now.
What to look for in a compact camera: wide angle lens, high iso performance, focus assist lamp and face recognition. I think the last two points are very important because the most useful function of a compact camera to me is taking photos of people in poor light at parties and when out on the town. These features should assist with getting good shots in those conditions.
And regarding the Panasonic FP1 and FP3, they are a different concept than the LX3. But the LX3 is relatively bulky with the lens cap on the chunky lens.
