I was worried about the durability of the folding card too. It does seem rather flimsy but I thought a would buy one, in anticipation of a long Aegean vacation, to torture test it in as many adverse conditions as possible before committing to a 2GB model.
So far, it is doing fine. I have have had it in and out of the camera and computer hundreds of times with no adverse effects. I find myself downloading much more often because it is so easy. This is very handy when I am testing lens or doing any other kind of technical evaluations. Its not uncommon to download the card when it only has a dozen or less picture files on it.
Since the 1GB card holds 100 raw files, I only need to use a 2nd card (a regular non-folder) when I am out in the field really taking pictures. If I purchase a 2nd "PLUS" card of the 2GB variety, I will have a total of 3GB of folder type and 1GB of conventional Ultra II for backup. I'm also bringing my Epson P-4000 for an additional 80GB of memory for my trip (and viewing pleasure). That ought to hold me!!
I've had absolutely no trouble with any of my Sandisk Ultra II cards of either variety. I just hope the 2GB capacity one will be as trouble free. I am about to make the plunge and find out.
