The perfect camera does not exist, you need to decide which features are most important to you. I do not travel with DSLRs, they are too heavy and several lenses make the package even heavier.

My second travel digital replaced an older point and shoot, I wanted more zoom for wildlife. I bought a Pentax X-90 (discontinued model, current eqquivalent is the Pentax X-5) which has a huge amount of zoom, it is one of a class of camera called superzooms. Have used this camera for several bike tours, Europe trips and canoe trips. But, not waterproof. This won't fit in a pocket, but is much more compact than a DSLR with comparable zoom power.

My third travel digital I bought this past fall when I decided that I wanted to take more photos in wet weather. The Pentax WG-3 is waterproof and works great. A bit bulky in a pocket, but it does fit. It came with a little ring that clips on the front for macro use but I found out that I can fit a polarizer on it, I think it takes a 46mm filter.

On camping trips and tours I now bring both the superzoom and the waterproof.

In both cases above, I bought several spare batteries on ebay, new shipped from China. These usually have lower life but cost a small fraction of the branded batteries.

Olympus also makes some highly rated waterproof cameras, a friend of mine has one and he really likes it.
