I have been using the Wing for a couple of months now and I am fully satisfied with my purchase. The hardware is of reasonable quality, and I expect it to last for years. The touchscreen is the best touch screen I have tried on a mixer, mainly due to its large size, and the UI is extremely well designed.
If 96K sound quality is important to you, Allen Heath SQ5 is also a good option, but if you are like me, and think 48K is plenty, you will get much more value for money with the Wing. The SQ5 requires you to buy many effects separately, with the Wing they are all free.
If you are touring, this mixer it quite large, and you might want to wait for the rack version. However, if you have the means of transportation, you get a very powerful live solution.
What you don't get: The screen has a plastic surface, not glass like an iPad. The faders are okay but not as awesome as the Midas M32 faders. The mixer has two headphone output jacks, but they transmit the same signal, meaning you cannot really work to people at once as advertised. The firmware is not fully complete, but complete enough to be used for live concerts, and the updates are coming bimonthly.
Still, this is a truly awesome product, and I highly recommend it.
