Why not keep both?
My Mini is my travel device. My iPad is my home device. The Mini is what I use in the airport, in the car, at the coffee shop. The iPad is what I use at home, in the office, in the hotel room.
The whole specs argument is somewhat disingenuous. For the Mini, it's all about form factor. Think about it like you would comparing a desktop to a laptop. Of course the desktop has better specs. But you can't put the desktop in your briefcase. Or use Steve Jobs trucks/cars, heavy lifting allegory.
Enjoy your Mini!
