For track day purposes I don't think a tablet will cut it because anything not tied down in a event of a crash is just another potential missile to the cranium. I have the RacePak IQ3 only because I bought mine new back in 2009 but never used it until only last year. I am pretty sure they have a Vnet interface that will tie in your MS3.

The RacePak stuff is good for street use but I find the datalogging is complicated compared to what you can get for free on your typical smartphone apps. There are display dashes like the AIM MXL2 that have great features that should tie into your MS3 setup also, but are way up in price
