"This Life and Later Ones" by George Zebrowski

First appeared in Analog. Reprinted by Karie Jacobson, James Frenkel.

Summary:

A man's father chose electronic immortality, but it's boring.  It doesn't feel real. Other residents agree.

The son tries to work it out for the father that he gets a new body....

Spoiler/Commentary:

They agree, but the solution doesn't change anything:  Part of the father remains in the computer still, still complaining, forcing son to continue visits.

One of Zebrowski's best--a good marriage of idea and emotive storytelling.
