The GF3 is a very nice compact yet capable camera – I was sorely tempted when they were being sold off at discount in so many places online. I certainly don’t doubt I could have taken any of my recent shots with one just as well. For many keen amateurs without a legacy lens investment, I suspect mirrorless would suit them better than a DSLR, especially if travelling.
Interesting that you “don’t miss the viewfinder”; I find I instinctively want to put the camera to my face, and although the D50’s viewfinder is very poor by any stretch, I’d much rather use one than hold the camera out in my arms. This might be because the GFs put me in mind of rangefinders, and then I want to use them like one.
I’ve added an update about my GF1, based on further experience: http://www.big-bubbles.fluff.org/blogs/bubbles/blog/2013/05/01/the-future-is-mirrorless-probably/
