I'm still using my iPad 1, running 2.1.1, docked as a backup. It still works well although, when I use it wirelessly, I notice a slight delay in the response from the mixer compared to the iPad Mini that I use FOH. I will probably swap it out with my wife's iPad 2 when MF no longer supports it since she has GAS for the iPad Air. That being said, if I only had the iPad 1 right now, I would still be content using it wirelessly for the gigs I cover. I use an Apple express for WiFi and it's performed flawlessly for the last 17 months.
