I cannot imagine my life without my MacBook. It is literally the best thing that ever happened to me. Its so easy, fast and just convenient to use. For my job I use a Dell computer and honestly just for my peace of mind I find myself using my personal MacBook during the workday just because it is so much easier for me to maneuver. They also last forever. I can honestly say my Mac works just as great as the day I bought it 2 years ago. Last thing, I feel like the battery life is better on my Mac vs my Dell work computer.
I love my MacBook Pro and will only replace with another when the time comes.
