Yes, inertia is a main cause of turbo lag, and keeping the turbine close
to the exhaust manifold does help to decrease lag.  But you forgot to
mention another problem that causes lag-- the turbine's distance from
the *intake* manifold.  This is a major problem, especially when adding
an "air-to-air" type intercooler to the system.  If there is a large
amount of tubing at the output of the compressor, then there is a large volume
of air to be compressed, which takes a while.  Many tight bends in the
tubing are undesirable as well, since they add resistance to the system.

The bottom line is, for minimum lag, keep *all* plumbing to/from the
turbo unit as short and straight as possible!

Or maybe not...
