Weather Sealing
Unfortunately neither Panasonic Lumix DMC-ZS3 (Lumix DMC-TZ7) nor Sony Cyber-shot DSC-HX1 provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.

On the other hand, Sony HX1 features a
Tilting screen where you can change the angle of the screen to make it easier to shoot from waist or over the head levels whereas the Panasonic ZS3 has a fixed type screen which provides less flexibility in shooting positions compared to HX1.
