Neither Nexus 7 nor iPad Mini have memory expansion options given the common sense definition that most people use when describing memory expansion.
If the option for expandable memory is a requirement (the OP has not stated that it is) then it would be helpful to point out the fact that there ARE 7" tablets that provide for microSD card slots such as the Samsung Galaxy Tab 2 7.
Having said that, if it comes strictly down to a choice between the Nexus 7 and iPad Mini, I would recommend the Nexus 7. (BTW, I'm not a fan of the N7) The openness of Android is a tremendous advantage (over iOS) for a device that is both mobile and personal. The ability to customize and configure a 7" tablet with widgets, icon placement, etc. can really enhance the usability of the device.
And without the ability to expand memory (* - traditional definition) try to get a model with as much memory as you can afford.
