13" Macbook Air and Mac Mini VS 15" Macbook Pro Retina

This is my first time on the forum so hopefully I'm presenting this question correctly!

I'm currently a freshman in college and at the end of the semester I'll be transferring into a broadcasting degree in another college. I've been thinking about buying the 15" Macbook Pro retina but have done some research and have been thinking about buying a Mac Mini and a Macbook Air.

Specs I'd get...

Macbook Pro retina 15":
i7 processor 2.6 ghz
16 gb RAM
256 gb SSD storage

-OR-

Mac Mini:
i7 processor 2.6 ghz
16 gb RAM
1 TB Fusion Drive

AND

Macbook Air 13":
i7 processor 2.0 ghz
8 gb RAM
256 gb SSD storage

Price isn't too much of an option to me. I will use it for Final cut pro X, Photoshop CS6, Pro Tools 10, Microsoft office, general browsing, and Minecraft map making. Also over the summer I will be traveling a lot, but once school starts I should stay put for the semester.

I figure if I got the Mac Mini and Macbook Air, that I could use the Mini for editing and the air for general activities and office.

I have a little while to decide but let me know what would be the better choice or if I should look into something else.

Thank you guys so much!!
