Hey Everyone - Just spent a couple of hours searching the threads for pros and cons for the current lineup of MacBooks. I currently use a PC desktop and work-issued PC laptop and have a good bit of experience upgrading PC desktops. I've never owned a personal laptop but can see myself transferring most of what I do on my desktop to the MacBook (Internet browsing, music downloading, financials, etc.). I don't play games on computers. I don't do any sort of video-editing or any other tasks that would require the best processor on Earth. I really just want the portability of a laptop with the reliability of an Apple in order to be able to do normal, day-to-day activities while not tied to my home office desktop. With all that being said, I'm looking to buy a new MacBook due to a friend's discount at the Apple Store. I have about 50GB of music and 20GB of digital copies of movies, but the music is really all I'll care much about. I have a 500GB USB drive that is currently connected to the desktop. Can it be formatted to run on both a MacBook and my PC? So, what's the verdict from some of the seasoned folks on here? Is the model with the retina display worth the extra cash? Will I absolutely miss out if I don't have an SSD? Thanks for the help.
