If you own a Canon P&S camera (or any camera for that matter), or are
considering buying a new camera and don't know about CHDK, you owe it to
yourself to see what CHDK can do. No other cameras in existence, DSLRs included,
are capable of what a CHDK-compatible camera can do today.



The SD700 / IXUS800 IS version of CHDK is in preliminary beta phase but appears
to be working (from reports so far).
