I got my MBP yesterday and it is... simply amazing. I'm enjoying everything about OS X. I LOVE the trackpad gestures as I am able to use my deformed right hand to do simple tasks. I love the dock bar, the animations, full screen apps, switching between full screen apps, time machine, etc. This is EASILY the best purchase I've ever made. What do I like most? Editing photos on a properly calibrated display. The retina display really makes this wonderful! I cannot go back to PC for editing. There has been a learning curve with few things, particularly installing apps and keyboard shortcuts. But I am sure I will have these down within a week of use. I want to thank everyone who helped convert me to Mac. It's brilliant!
