To the OP. Some great images! Thanks for posting...
I've had a strong pull towards the X10 for a while now. The orbs problem is probably hardware related (see DPR for some topical info) but there are so many other aspects/qualities about this camera that I really like, that I'm still considering it.
I'm torn between a Fuji and another system where I can use alt lenses though, so I may wait a while longer (and check the Fuji Pro at release). In the meantime. I love seeing images from this small, and beautiful camera.
