Sounds like all the MicroSoft complaints I've been hearing for decades.
Now where is the perfect mixer app? Who has seen the one app that has no problems, no quirks and no shortcomings running on the device that has no problems, no quirks and no shortcomings? I surely haven't seen it. And don't forget to add the perfect WiFi device that also has no problems, no quirks and no shortcomings. (Probably the most stable item involved and I had one crap out during a show. For that reason alone, I like the ability to dock the ipad. That is what saved me that day.)
