The E900 is an amazingly capable compact high resolution camera. At today's prices, it is just plain ridiculous. While it doesn't have the low ISO performance of the newer F30 type cameras, it can still shoot great ISO 800 jpegs that remain printable at 11X17 or so.
The lens is pretty sharp.
And more importantly the E900 can shoot RAW files which allows you to do all the image processing yourself. If you use S7Raw, a free RAW conversion program, it is even possible to create 18megapixel images from the RAW files. I've done some test shots at ISO 80 RAW, and have created some 18 meg tiff files that are really unbelievable in the amount of detail they capture.
The E900 is also a reasonable fast camera in startup and use, with very low shutter lag. The rubber grip and light weight make it very pleasant to handle, and it is easy to maintain a solid handhold.
AF can be a bit slow in dim light, but generally not a problem.
Both

Unfortunately dpreview never reviewed it. The link to imaging resource's review is

Imaging resource is along with dpreview, my most trusted technical review site.
Good luck, at the prices the E900 is at these days, I can't imagine anyone not having one. You can spend a whole lot more money and not get half the camera the E900 is. Just my opinion, of course.
