I found that using my 5-6lb 15" laptop in & out of the car for tuning/logging to be a little cramped, awkward or "gangly" at best.
So, I found a solution. Went to the Microsoft store & picked up this. I actually got the first one that even they've seen. Fresh out of the UPS shipment. It's a full i5 Windows Pro PC.
Now all I need is the wide band & we'll be in business!
