Coming from Windows, like many people I was a little afraid of being stuck on many applications and have paid a lot of app. And made not! For photos software user found that all have needs and ease of use is really disconcerting, it's a real treat. On the day of the reception I get into a format since I've replaced the hard drive with a Momentus XT Segeate 500gb 7200 (essential investment to increase the speed of the machine) and therefore handling is made finger in the nose compared to a Windows format! If not for its price, yes it is expensive but the quality is there and you'll get your money.
Basically I do not regret my purchase and would recommend it 200%. For people who have a priori on mac os x, forgotten ideas you received and your done you'll change your life!
