long time transcend user here, 4gb, then 8gb,( for panama cruise) i have 5 of those, purchased back in the spring for around the same price as the 4gb was last year (purchased for med cruise)
i've only had 1 bad card,a 2gb that came bad, would not format, camera could not even recognize it, right out of the box bad, immediately replaced at no cost to me by the vendor,zip zoom fly
i like my transcends, and in fact as long as the prices keep dropping and the cards get larger i see no reason to invest in a portable hard drive/viewer ala epson,wolverine, etc
especially since we all know about my oft stated paranoia about having a whole vacations worth of images going down the drain from a drive failure
a couple of $60 dollar cards look pretty cheap while on a $12000 cruise
just my .02 worth
addendum, i also feel a viewer/drive would not do anything for me, as it's been quite a few years since i slowed down long enough while on vacation to do any photo editing or review, if it's blurry on the camera lcd and that's not what i wanted it's deleted right then and there, otherwise it waits for home, and the 32 inch calibrated monitor, that's where i can really decide keeper or not
