Properly implemented, computer control will provide:

* Rotator control,
* Full Doppler correction.

And yes - you can rag-chew without turning too many dials but currently with 
FO-29 'resting' you'll only be able to use VO-52 and get up to 10-15 minutes 
quality time on a pass. (You shouldn't hog an FM-only satellite such as 
AO-51 or SO-50.)

P3E will be a different matter, you'll be able to talk for hours when it's 
visible.
