The need for a laptop (for me) has been reduced because of the internal ability of my keyboards to playback audio files directly. I prefer the audio coming out of my keyboard speakers anyway, so it's becoming more and more common for me to just DJ from the kb itself. The iPad is my juke box when I leave stage and go on break, or a quick internet connection for a request, but a laptop can do that too.
The new mini is just so darn CUTE, and fun to hold and play with. I absolutely love it.
