Been a windows guy since I found out what a computer is. Two days ago, I purchased a Macbook Air for school. This is one of the best things that has ever happened to me. I don't have a single problem that the author mentioned. He probably upgraded an old Mac to Lion and is having all these problems. I haven't had a single crash. Launchpad is a good thing to happen. There's no clutter when you are trying to look for an application. If you are thinking about purchasing a Mac with Lion or upgrading to Lion, don't believe this guy.
