Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Panasonic FX48 is 3g lighter than the Pentax I-10 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither Panasonic Lumix DMC-FX48 (Lumix DMC-FX40) nor Pentax Optio I-10 provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors. If weather sealing is a must-have feature for you, check these sections: Top Compact Cameras with Weather Sealing
LCD Screen Size and Features
Pentax I-10's 2.7" LCD screen is slightly larger than Panasonic FX48's 2.5" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
