The Lion OSX 10.7 on my Macbook Air is just awesome. Yes some apps are buggy and I am sure that they will get fixed over time, but overall it has been really good to me. I know some people think it is garbage. I know some of the folder management was weird (but can be changed back to more traditional file structure). I know I had to learn a whole Tai Chi like way of using the trackpad but it has been rewarding. Being a huge Keyboard shortcut user, having some slick functionality added to that trackpad has me coming back to it more now. The easy of navigating windows has me less and less using Command – Tab and more swipey uppy downy movements instead. More experimenting is on going right now but I just had to post because I needed to.
