All I can say is I've been VERY VERY impressed during the first 2 weeks of ownership of the Fuji S3 Pro - shots are a fair way better compared to my 2 previous DSLRs. (350D and D70S) .. Yes its a bit slow - but nothing much to worry about- especially if you use XD cards as they are twice as quick within this camera.
At the current price it can't be beaten in my opinion.
Benefits over D70S and Canon 350D:
Much better shots straight out of the camera in particular JPEGs, but RAWs also:
(i) Skin tones better than the 350D and MUCH MUCH better than D70S
(ii) Landscapes have a lot more impact - especially in the Film 2 mode (Velvia simulation)
and even after processing I couldn't get the D70S's landscapes to look as good
Much better Dynamic range - 2 extra stops of latitude/range over the D70S- thats rather a lot I can tell you.
Better larger and brighter viewfinder - Pentaprism vs Pentamirror
IMO better detail resolution than both the D70S and 350D
Has a portrait shutter button - so you don't have to fork out for a grip
Disadvantages
Rather heavy and bulky - although some would like this
RAW files in full dynamic range mode are very big - 25MB each, and on a compact flash card take about 8 seconds to write
Rather slow in RAW mode, in JPEG not too bad, takes less than a second to write to XD cards
I don't like the fact it uses AAs as I get about 200 shots to a set of 4 AAs vs about 900 shots on one charge of the D70S's batteries
It could be the amount of flash/previewing etc I've been using though, as some people have reported up to 800 shots or so
Here are some sample piccies all taken with 18-70 Nikon lens.
