Looking at the gallery in the OP, most of the features enabled by CHDK are standard in DSLRs anyway - RAW shooting, longer shutter speeds, full manual control, etc. As a DSLR shooter, I was looking through that gallery thinking, "what does CHDK allow that I can't already do with my camera?" until I realised they were doing it with P&S cameras.
