Efficiency = Time = Money. No matter what your needs, your electronics should serve you in the most effective manner possible. They are meant to improve your life, not frustrate it.
Optimization is the key to efficiency. It's about evaluating your situation and trimming the fat, introducing something new, or improving what already exists in order to make it better. With computers and gadgets in general, "better" means faster, easier to use, more versatile, and more secure. There is almost always room for improvement. Things shouldn't just work; they should work to their maximum potential.
