Jos,

>I have bought one and run our app from it and it works just great. Performance is very decent and will achieve the desired effect which is to show-off the ability for our app to run without any installation, from any PC or laptop with a USB port, without any special hardware or installation routines, and without modifying the users environment. Gotta love VFP :)

>The reason we are looking at this particular flash drive is its flashiness (pardon the pun). We are going to buy 20+ of these cards, copy our application and 1.5Gb database onto them, and brand the card with our company logo. When we do a demo to a corporate client they invariable ask for a trial installation. Now the marketing guy can just pull out his wallet, take out this credit card sized drive and hand it over and say "there you go, knock yourself out!". Its just a marketing gimmick.

seems I guessed into the right direction - the moment a techie asks about "sleek devices" think demo<g>. I think this is a great idea. Just 2 points: if you plan to regularly run from external disks you should look into adding firewire and e-SATA external devices to your "reccommended" list.
The data transfer via USB has a much higher CPU cost than Firewire (and also slightly worse performance when using the same disk). Connecting via e-SATA should give you the performance of an internal disk. Probably not necessary, but store the info into the salesmen as well to prepare them for loaded questions intended to stop your project, along with the prepared answer to such questions (with numbers for "techie trouble makers" <bg>).
Point 2: as much as I personally LOVE working with USB devices (collection of 3 sticks of and 4 disks) be prepared that sometimes your plan might not work because corporate USB ports are off limits or even sealed. In some environments the "security experts" try to make the machines "safe" by disabling DVD/burners and closing USB ports. If the security expert is clever enough to use low tech (glue) he can be pretty effective... The salesman should still have a laptop at least in his car to be prepared for such situations. And be certain the security hassles will get worse, even if your typical decision makers are not always bound to follow the strict rules.

Best of luck
