Hello! I am currently in the preparation stages for my first foray into the Mac world. Next month I'll be buying a 13.3" MBP with an i5 (2.6ghz) processor, 16gb of ram, and a 256gb SSD. So far, I've subscribed to iTunes Match and am currently in the process of uploading my entire music library. I've also made a list of apps that I'll need to get ASAP to enjoy the experience. What I worry about, however, is the learning curve involved with going from Windows to OSX. Do any of you have any tips that could help me before I actually get it? Videos to watch? More app recommendations? I need excellent apps for video playback for all sorts of file types, including h264 matroska files. Also, I instant message frequently, so a client that allows AIM and logs history would be phenomenal. Thanks for all your help!
