I thinnk JVC always cmae out ahead of othe rbrand smaller digicam...
However, some cheppo taiwan brand digcam also very small in size but in term of features .. obviously, u should to those branded one loh!
i'd recommend casio exilim or minolta dimage Xt. they're small (slightly thicker & longer than credit card) & fast to boot up & shut down since they do not have lens to expand. for casio, it has a docking station. & as far as i know, they're very fast at capturing images. for more details, read the review
I'm using the Exilim EX-S3 now...Kinda cool =)
But I recommend the Exilim Z4...Better and more functions compared to mine...Took the EX-S3 cause it was really super small and thin...Not available in Malaysian market yet...Can try Singapore...I think they got it not too sure =)
