I've been using a Mackie DL1608 & iPads for a year now with my own bands and as an independant PA man. It's brilliant. Proper Logic style EQs wipe the floor with the traditional Bass/Mid/Treble found on analogue desks. And I have 6 auxes. The interface is easy to navigate and it didn't take me long to get to know it. Actually, I'd downloaded the free app before I got the mixer & iPad so I knew how it worked before I even had the hardware. I even use it on bigger 7+ piece bands down to small 3 piece pub gigs because it's just so good. You can save everything - EQs, comps, gates, whole channel strips, complete mixes (incl auxes), which makes life really easy.
The wireless mixing thing isn't for everyone, but I'm sticking with my Mackie.
