Available elsewhere
I have the same issue: Pending order at OWC, now moved to 19 days to ship. I spoke with a CSR who said that they got a notification from Seagate that they were delayed.
It's available, though, elsewhere, but I wonder if it might be best to wait for this next shipment--if there are some mfr improvements made along the line, etc? Sounds sort of hokey, but if not I'm going to cancel my macsales order and order from another retailer.
