Torque screwdrivers are very specialized and often are expensive for just one fixed setting or multiple settings. I cannot think of an electronics application that would need this. I have read automotive and motorcycle engine carburetor and fuel injection repair might need a torque screwdriver. Space satellite assembly might call for a torque screw driver. I have worked on some microscopes, but just a good tip fitting screw driver is all that is necessary, not a torque screw driver.
First of all there is no choice about getting a tool or not, if the circumstances demands it.
And I am aware of examples that the torque screwdriver it is a must have.
Mobile phone repairs ( the sony ericsson assembly manuals are loaded with torque values )
Digital cameras - Video cameras - PDA ( anything portable and small needs Torque screwdrivers )
As electric screwdriver I use one battery powered Bosch ( screwdriver / Power drill)
At the front of it there is an special ring that acts as torque adjustment with settings of 1-5 + Drill mode.
I could say that if I had something similar in the form of a hand tool, I would be happy.
I had rebuild my motorcycle, and even had become famous about it ..

by doing an cheap and smart trick.
I got an very expensive set of bondhus allen key (Hex key ),
the very extra long version, so to control and sense the force by hand.
It worked nicely, all the screws at both left and right engine covers, got in place nicely, no oil or water leakage.
Professional results and perfect work all the way.
There are not many electronics application that needs an impact screw driver.
True ... even if I have one of the best sets of them, I have never use it on electronics.
And the damn bits for it are so expensive.
