First, the operating system is that much better than windows. It does take a little getting used to if you aren't familiar with Macs, but once you get a good feel for where everything is located you realize that the system is much more intuitive and geared to the user than windows. The battery life is outstanding, the processor is incredibly fast, and if you get a solid state hard drive the thing is indestructible. I can't tell you how many times I've dropped mine with zero problems.
This is my first foray in the world of Apple after many years of dedicated PC ownership. So far I have been tremendously impressed with the new MacBook Pro. I got the i7 processor and the 7200 RPM 500GB hard drive as upgrades. I'm extremely happy with this purchase and have not regretted it at all. I am becoming a little more of a convert each day to OS X and just how easy it makes things. The thoughtful touches on the multi-touch trackpad alone are amazing to me. I come into work and feel frustrated that I cannot accomplish the same things with such ease.
