has anyone used a Olympus 720 or 700??...forget the number I forgot it, but itīs some waterproof/shockproof one...

just the other day I saw them and was wondering how good are they.....compared to the Canon SD1000......

there is not much difference in price and capability... but the olympus has the waterproof and shockproof thing....

what I wonder is would it be worth it??
