It really depends on how you plan on using it day to day, and if you have access to a computer, smart phone, etc.
I have both an iPad 3 and an iPad Mini (and MBA and iPhone 5)
I use the iPad 3 and iPad Mini for different things
You have to decide what makes sense for you
I use my iPad 3 with a Logitech Ultrathin Keyboard and it works great for things like Evernote and such
I use my iPad Mini for reading, email, etc.
I would hate to give up either of mine actually
In your case, an iPad Mini would prolly be awesome and just what you need
But only you know how you plan to use it
Edit: And congratulations on the win and thank you for your service!
