A Vast Improvement on the E500

I also purchased the e510 as an upgrade to the e500 and unlike konoimo, I'm very impressed! I feared that the Image Stabiliser and Live View would be gimmicks but both have already proved very useful and really do work! The IS results in much clearer, sharper images at slower shutter speeds but let's be honest, No technology will correct a shakey hand!
The Live View allows you to focus or zoom in, on any area of the frame via the screen, which will also display settings, grid lines and even a live histogram. Under bright conditions the screen becomes more difficult to see but this is a common problem on most digitals, at least with a DSLR you can resort to the viewfinder.
I found with the e500, that once I had the menu set up correctly to produce the images and levels of sharpness, noise & colours that I expected, it gave excellent results. It's main problem for me was the unacceptable noise levels at higher ISO settings or in low light. These noise levels are far more acceptable on the e510
The e510 also offers a more comprehensive menu which I believe, when set up correctly, solves most of the problems konoimo has noted.
I never have been a great fan of in camera flashes and the e510 is no better than any other but when connected to my FL50 Flashgun, the results are very pleasing.
Needless to say, to date, I am well pleased with the e510 and have found only two minor problems. 1, Live View appears to drain the battery quicker, so be prepared to buy a couple of spares.
2. Still only three focusing points but at least it's less complicated.
My Verdict....... Add a couple of fast Prime Lenses and either the FL36 or FL50 Flashgun to your wishlist and I can't think of a better system, Enjoy
