You are all looking at this the wrong way. This is a solution for kiosks that might normally use Compact Flash plugged directly into an IDE (PATA) port. Since IDE is going the way of the Dodo, vendors need other solutions for small, reliable storage. Since I don't think any existing flash solution utilizes the SATA protocol (CF natively used IDE), this is a viable solution for people looking to update their systems.
Oh crap, I guess I missed the very last line. If this is for kiosks, why are they selling it at Walmart?
Ok, new solution. This is for Windows Readyboost. I mean, I have an old 2GB flash drive sticking out the back of my computer for just this purpose. It might be nice (if the price is right) to instead house that flash drive internally where it wasn't at risk of falling out or breaking off. Yeah, that sounds reasonable.
