I too wanna thank GrAnd, Vitaly and all the others that have improved the CHDK.
I bought my A710 recently, when the A650 came out and I was in a real dilemma as wether to get the "stock" A650 or the tweakable A710. in the end even though I don't have the same image quality, flip screen and lcd, I'm still glad I bought a CHDK camera (one of the last A710s around here). CHDK was obviously the reason why I gave up on those hardware benefits.
I like it that just like my smartphone, now my camera keeps getting more and more interesting as opposed to me getting bored with it.
though it wasn't my intention until recently, I seem to be slightly getting into little programming changes now
that's how interested I've gotten into it.
