Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.

LCD Screen Size and Features
Casio EX-10's 3.50" LCD screen is slightly larger than Pentax WG-3's 3" screen.
In addition to the size advantage, Casio EX-10 LCD screen also has a
Tilting feature where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels. On the other hand, Pentax WG-3 has a fixed type screen which provides less flexibility in shooting positions compared to EX-10.
