VSCO is not worth it if you know how to use Lightroom or Photoshop. You can imagine what you want and then adjust the sliders accordingly. It's for people whoa are too lazy to learn how to use this program, or people who are no invested into photography and just want to take pictures, run them through VSCO and upload them on facebook. I can't seriously believe that a professional photographer sucks so bad at either of these programs that he can't make the preset he wants. And after all, whether you call like Rollei ABC12 film or Fuji Superia 200 film, it's just a name. I think professional or naturally talented photographer know what 'look' they want and can tell how they need to remap the colors their camera produces into the look they want. But well in the age of instant, I'm sure their business will thrive.
It's simply because the maximum output of light from the EVF is much lower than the actually light from the sun. Thus your eyes are adapting to the ambient light, your pupils contract and you can't see the dim light from the EVF. You will experience this on all EVFs, but some EVFs may be designed better to cup your eye blocking off the light, which achieves the same results as cupping your eye and the EVF with your hand.
I don't think there is such a thing a 'bad' bokeh. It's what kind of out of focus distortion you would like to see. If you have seen pictures and you don't think bokeh it produces, then for sure you won't like the x10. It just won't feel right no matter how good someone else thinks it is.
I'll chip in and say keep the x10 unless you're getting a really good deal for it. I sold mine for the x100 and then that for the x e1. Now I want back the x10 as my everywhere camera since carrying the thousand dollar x e1 to dangerous locations doesn't seem too appealing.
