How Do You Do THAT?

So, I've got my pretty black MacBook. I honestly love it. The transition from a PC to a Mac has been fairly seamless. BUT, notice that was a BIG BUT...in order to make sure all my pictures, movies, files, and music made its way safely onto my new Mac, I've spent a lot of hours checking...and re-checking....and then checking one last time. I closed the lid of my Dell for the last time today. Man I hope I got it all...hmmm, does this expose my lack of organization? It mustn't...surely. Okay, I'll probably not blog any more about the Mac...it's obnoxious to you lowly PC users! HA!
