Very well put, Dan.
I love my ipad. I use it a lot in my DJ business. I use it for presentations to clients and to enter client info at a meeting. At the event, my ipad is in incredible tool. I use it for Mcing. I used to have just a printed sheet of paper that I made changes to with a pen. Now, I can make changes right on the ipad and then use an app called teleprompter+ and all the names are HUGE and they scroll and are lit up.
It's also a good remote. With an app called splashtop, I can completely control my computer from my ipad. It just needs some type of wireless connection. I haven't tried this way yet, but i'm told that even a wireless router that has no internet connection will work to connect the 2.
The beauty of the ipad is it's portability. At least at this point, if using it for Djing, it would need to be plugged in to something, and you'd lose the portability, so you wouldn't be gaining any advantage over a laptop.
