Mid-size Travel Camera

For traveling, it is useful to have a mid-size camera. Something with a good zoom lens, but smaller than a big DSLR. This is in addition to a small pocket camera (or cameraphone) that you just keep in your pocket. I have a Sony DSC-H5, which I like, except that it takes AA batteries - I want a lithium ion battery instead, so I can recharge whenever I want. I'm also considering the smallest DSLR for this purpose - the Olympus E-420. Camera specifications are from dpreview.com.
