When you are going to travel with your camera regularly, you'll need to think about its weight and volume.

In many cases, it's hard to envision the gap between sensor dimensions simply by going over a spec sheet. The picture here might offer you a better sense of the sensor dimensions in the GH1 and H90.

As you can see, both of those cameras have got the exact same resolution albeit not the same sensor dimensions. The GH1 includes the bigger sensor which should make obtaining shallow depth of field less difficult.
