I have both the slip case that comes directly from apple as well as I just purchased a few weeks ago a Zagg Mate keyboard/case. I find for general carry around the office to meetings and such the apple case works real well, light offers someprotection and adds no real weight. The Zagg mate on the other hans I use to enter notes or long emails and usally use it at home or where I have some room to work. Works great for this. If a simple light case that looks good, then go with the apple, if you need a little more protection and the ability to have a keyboard handy, the Zaggmate is the way to go.
