since January, waiting for Samsung to ship this SpinPoint M6 500GB, 9.5mm laptop drive wonder. That whole "released in France" thing was just rubbing it in your face, and we apologize, but it looks like your wait is finally over: OWC's Woot! shop has the drive for sale as of now. You can't buy one sans enclosure, but the $310 USB 2.0 + eSATA version or the $350 FireWire 800 / 400 + USB 2.0 version (there's also a $320 model) should prove useful in housing an old 2.5-inch drive, or perhaps an ant farm.
