I've got a GF1 which is an excellent model, and nice and compact, especially with the 20mm 1.7, but I have to admit I don't use it nearly as much as my GH1. I just find the lack of a built-in viewfinder to be a major shortcoming. I do have the LVF 1, but it's a bit of a nuisance to use, and the image viewing quality is nothing to write home about. It may be my ancient eyes, but I find it difficult to compose the picture on the LCD screen, and the LVF 1 is nowhere as clear as the excellent viewfinder on the GH1. To employ a cliche, is it just me?
