Drawbacks include slower acceleration and more jetblast when getting the aircraft moving from a stop. Fuel burn must be managed if using a wing tank.
An APU should be running as a backup source of power and air.
Is it real tough to keep straight?
No.
Do you save a significant amount of fuel?
On a long taxi, yes.
Can aircraft like the 747 and MD-11 only use one engine on each wing and taxi and save fuel?
Yes.
I also have one thing to add to mikes comment that can save fuel. How about asking for and taking shortcuts in the air? Some pilots do it all the time, and some pilots turn it down even when ATC offers it to them.
Sometimes, a direct route costs fuel by encountering unfavorable winds or a turbulent area which your dispatcher had planned for you to avoid.
