Mind over Machine from the Core book, and MMRI from Data Trails, do the exact same things. The difference being that MMRI explicitly states it does not come with a datacable. The reason for which, was b/c everybody kept asking about whether MoM from the Core was supposed to, since it gives "the benefits of a control rig".
In that same regard, when you guys are seeing "it's kinda like a free datajack", you're reading WAY into that and coming out with the notion that you get the datajack Wireless bonus.
