Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Pentax WG-10 is 22g lighter than the Nikon P300 but we don't think this will make a significant difference.

Nikon P300's 3.00" LCD screen is slightly larger than Pentax WG-10's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
