why should i buy Xacti C5 when i can buy Exilim Ex-S500 w/ s

[msafi]

i guess thesubject and the description says it all.

i was interested in the Xacti C5, but theni realized that there are smaller digital cameras that can record videos in VGA resolution with 30fps. just like the C5.

what sets the C5 aside? should i just buy a regular digicam with good movie quality like the Exilim Ex-S500?

any other suggestions?

thanks,
