The crystal ball tells me that SSD adoption will kick this date a little
farther into the future given that SSD capacity lags mechanical by a large
margin.  In the not too distance future, PCs/laptops/netbooks will all
transition to shipping with SSD as their sole/main internal storage device,
with USB3/eSATA thumb drives of 1TB and above permanently replacing external
USB/eSATA mechanical drives.

Servers will probably transition at about the same time to shipping with
solely SSD storage internally for boot/OS and maybe some other primary and a
little secondary storage, with mechanical storage being optional, whether
internal or external.  Mechanical in the form of FC/iSCSI SAN and NAS arrays
will still rule large data needs well after the aforementioned transitions above.
