Anyone switch from G/GH camera to GX1 or smaller PEN?

After getting the GF3, I really starting like the size and in my testings works surprisingly decently with with my adapted MF lenses. Now this has kind of got me thinking maybe sell of the GF3, and G2 I have and exclusively use the GX1. I want to see the opinions of users who went from G or GH series camera to the GX1(I guess GF1/2 could work as it does have evf port and hot shoe) or E-PM1/2. E-PL3/5? Do you miss the articulating display? Is the lack of an evf an issue? Any other comments or tips?

I like to do wildlife photography, and more recently have some need to go into street shooting. So, I know it would be a bit hard without an EVF, but these models do offer an optional one if I felt the need? If you ask why not go G3, it's because I want something jacket pocketable, which the GX1 or newer PENs still would be.  Thanks.
