Reply to Convince me not to get a z1

I really want a to-go sound card to go next to my midifighter 3d, but heres the issue: I also want a second controller for volumes and eqs when I can't bring my whole setup, but only have two usb ports on my macbook and don't really want a usb hub. the z1 seems perfect, and I can even change the mapping to work as a controller for decks c and d when i have it next to my z2, but seriously, convince me otherwise please! what ever happened to the midi fighter x???
