I bought a Mac Mini yesterday and have been looking around for a USB hub. I've done some research and notice some complaints from unpowered USB hubs while others find them fine. Since I know there must be some people here with experience with both, I thought I'd ask. Unpowered hubs are considerably cheaper. The only things I have really are a keyboard, mouse, digital camera, and printer (which has its own power supply). Maybe an old webcam. I know an unpowered hub would work with a mouse and keyboard just fine, I only worry about my digital camera and printer (even though, as I said, it has its own power supply). I also have an iPod but I suppose I'll just make use of my Firewire port from now on. This is my first Mac, and I love it.
