A colleague bought the Sony 707 and *really* liked it - he reckoned it was a fantastic bit of kit, "the best gadget I have ever owned" or something. Unfortunately, he had a few "lemons" and went through about four cameras with problems ranging from bad pixels in the CCD to a strangely curly hair in the viewfinder (!)
He eventually went without after the last one as he had money problems, but he is looking at getting the 717 now - so am I actually.
I currently have a Nikon CP990 and very much like it, the Nikon 5700 is on my list of cameras to look at, I would love the D1X though £2,500 is a bit out of my range :-(
