I'm late to the thread, but have a good observation. The Allen & Heath Mixwizard4 14.2 has an aftermarket add-on available. You can add a USB 2.0 board to the mixer which will route all 16 channels to your laptop DAW. Cost about $300, available on eBay. I know it works as I added the board myself. Note, you must open up the Mixwizard yourself, screw in the board and configure it - not easy, because you have to cram it in a tight space. But, what a great feature if you're interested in more inputs of decent preamps vs fewer higher quality inputs via interface.
