I think it's a good review, and it looks like Fuji have addressed one of the weaknesses of the x10 - AF speed and accuracy. However, the loss of EXR mode (especially the DR benefits) probably doesn't make up for it, for me.
My view of the samples is that IQ is fractionally behind competitors (at low ISO), but basically in the same range.
If there's one thing I've learned, it's that small differences in IQ in 100% crops just aren't a major issue when selecting a camera. AF, viewfinder, ergonomics (inc. menus etc) can make the difference between a shot ruined/missed, and a shot that's good. After that, a small difference in IQ just isn't that much of a big deal.
At the price, it's not worth trading in my X10 for, but it looks like a good camera for many enthusiasts. The manual zoom alone makes up for the slight softness IMO.
It's a tricky area. A friend who is print maker re-printed a limited run of one of her etchings, justifying it by using sepia rather than black ink, and thereby creating a new work. But I know some artists would consider this slightly dubious.
I think it's even harder with photographs, where it so easy to change the size/tint/crop/whatever and create a 'new' print run.
When an artist finally creates a commercially successful image, there must be great temptation to cash in on it.
