What camera?

I've been thinking of getting a new camera for use in the Dominican Republic. I really want something better than my phone camera, the 3.2 Mpixel k800i, so that I can make another photo book like I did with my photos from my European travels last summer. I was thinking of getting the canon Digital ixus 70 for a while. The orientation sensor was a great feature which would save rotating the photos once I put them on the computer and the smaller screen than the ixus 75 means extended battery life.

Now i've found the Pentax optio w30 which looks like the camera i've been looking for. Designed to be rugged the camera is waterproof to 3 meters for 2 hours. This alone makes it tonnes more suitable for going adventure touring in the DR. There are drawbacks, of course, the optical zoom is only 3x as it has to use a refraction lens because of the waterproof shell. There is no orientation sensor and the camera is around £175. However it is 7 Mpixels and the sample pictures seem ok. There is a coating on the screen to make it visible in bright sunlight and the underwater pictures will be stunning in the clear Carribean sea. I think these things make up for its downfalls and I can always sell it afterwards to get some of the money back. Who doesn't want a waterproof digital camera?
