The relaunch books have apparently gone to great lengths to undo Trip's death.
Me, I just ignore it. After all, it's just a holodeck programme done by Troi, of all people (not exactly an electronics genius) and since continuity is ignored pretty consistently throughout the entire episode (Trip never went to college? Hoshi could hardly understand him at first? He calls Archer "boss"? As evay said on triphammered, who are these pod people?).
I think you'll find that most fans (a) hate the episode with a pure and holy hatred and (b) don't think Trip is dead.
