I am getting an iPad. I am looking between the iPad 4 refurb from Apple for $339.99 CAD and the iPad Mini Retina Display for $419.99 CAD. I was thinking the iPad Mini Retina would be a bit more future proof plus the form factor is beneficial. I also like the idea of a 64 bit processor. Is it worth the extra $80 CAD? I also want to know what benefits besides the bigger screen if I go with the iPad 4? I had the 4, but I sold it to a friend to get $ for a PS4. Now, I am back in the market for the iPad. Thoughts?
