If you already have an iPad, would you buy a Mini also?
I probably would have bought one but got tired of waiting for a good 7" tablet until the Nexus7 came around.
I needed something smaller than a laptop and larger than my phone.
The last time I traveled it was perfect. Fit in my coat pocket. Easily handled email and even remote desktop into work.
Not a comment on the N7, but reflecting on the size.
It's a shame Apple waited this long to recognize a need for something in between.
