Glad no one is upset I moved us along. I agree with the comments on the Presonus, you do need the mac to use the iPAd remote and you need it for anything advanced above mixing such as backups of settings or recording. BTW the Mackie allows a stereo recording of the FOH mix right to the ipad. I gather you need a DAW program to really be able to listen to it but that is a cool feature.
Some pro's on the Presonus is the flexibility in outputs. It has 4 aux outs, stereo out, mono out, control room out and headphone out. I do miss these in the Mackie which has 6 aux outs, stereo out and headphone out. But you must choose the features that are important to you and go for it.
Cheers
