Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Pentax VS20 is significantly lighter (149g ) than the Casio EX-10 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Casio Exilim EX-10 nor Pentax Optio VS20 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Casio EX-10's 3.50" LCD screen is slightly larger than Pentax VS20'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 VS20 has a fixed type screen which provides less flexibility in shooting positions compared to EX-10.
