Yeah, on second thought it does look more useable than lx3, however those samples of hte lx3 you posted are nowhere NEAR a normal iso 1600 shot from an lx3, they are horribly underexposed and thus extremely noisy. Even my wife's little LS3 produces much much better iso 1600 shots than the lx3 examples posted. Like if you took a picture of that cat it's exposed correctly, if you look at those lx3 iso 1600 samples they aren't at all. Especially that second one. Even an SLR is going to be pretty noisy if you do that to it.
The LX3 also has a much faster lens though which in this case is going to negate any iso advantage imho....
This Fuji has a much higher zoom range though and looks much bigger physically than an lx3. I think the correct thing to compare it to is the G10...
And in that case it looks like it might be: if you NEED the more useable iso 800 and 1600, get this thing, if you shoot mostly iso 80-400 grab the G10. Will depend on price though of course. The other problem is fuji is just awful to work with as a company, so we'll see. ^_^
