I agree, and it's not that I don't like the Mini, and for all I know, I'll end up with one as well, although I've really come to like the plastic-backed tablets due to their better innate comfort.But what makes it better than iPad? Cheap price? Yes but there are trade offs. Maybe it doesn't matter to you but it's worth noting.
But the fact that it is cheaper - I mean, look, a 32GB cellular model is still $30 less than the 16GB WiFi iPad Mini - is a huge deal (provided it does what you want, granted).
If I needed yet another iOS device, or if I had no such devices, the iPad Mini would be worth the price to me. With all my various devices, I don't need another one from Apple right now, so the facts the N7 does all I want, costs less, and does things I can't do in iOS make it compelling to me.
But yes, there are equally good reasons to get the Mini. The only important thing is that people be happy with the device(s) they choose, and, lucky for use, there's a metric crapload of relatively cheap devices that are all pretty damned amazing given where things were even a few years ago.
