I now have a Canon, but it’s all beat up and is getting a bit slow. What are the good brands for digital cameras?

How come all digital cameras use this system for storing photos?

Root directory: DCIM (and sometimes MISC)
Inside DCIM: 100xxxxx (Five letter word like NIKON, CANON, PENTX, CASIO….)

What is the “Misc” folder for?

What does “DCIM” stand for?

Why exactly five digits after “100″?

Who set this standard for all digital cameras?

Thanks for answering this dumb question!

I am looking to buy a GOOD digital camera. I have been researching and have narrowed it down to two choices. The Canon Powershot S3 IS, and the Sony Cyber-shot H5. If you have one of these cameras please give me your opinion on it, the pros and cons. I have read mixed reviews on both cameras.
