Linda,
I've held the Olympus E-1 in my hands and it is a serious piece of machinery. It has a lot of heft and doesn't feel plastic and light like some of the new cameras. However, I think it's going to have a hard time competing from this point on because it's price is $1799 body only.
The new competition D-SLR's with comparable features, like the Nikon D70 is $999 body only. And the Digital Rebel by Canon is $999 with a lens. The Nikon also comes optionally as a kit that includes a very fine zoom lens for a total of $1299.
This stuff is always in a constant state of flux.
