My wife loved Acer because they were cheap. After the second black screen of death, I finally convinced her to go to an Apple. It really works better for what she needs it for and does much better with balancing her resource draining programs without significant performance loss. Of course, Apple isn't cheap, but to me, the price is worth the performance.
When you move from a $250 Acer to a $3000 Apple product you would expect the performance to be better.
