A comment on remote v.s. local data storage:

As it looks like very large amounts of storage will (and are) available
in some very small packages it may be beneficial to carry all of your
data with you.  Assuming your storage device had some sort of local area
wireless connectivity you could make virtually any computer you come in
to contact with (whether wearable, desktop, pda, etc.) "your" computer
complete with your data and applications.  Additionally you would have
access to ALL of your data no matter what type of WAN connection was
available to you at the time.

Other than the (current) issue of relatively low wireless data-transfer
rate, what do you all think the other downsides to a purely local data
scheme would be? (Admittedly you could just plug it in to a USB port or
something, but a wireless interface seems much more novel and
versatile).
