I don't even see it as a "manly" thing. It's just one device is far superior in every way to the other. And the other is cuter. It would be a totally different story if the iPad mini had a retina display and A6X processor and cost $100 less than the full-size iPad. Then I could see a realistic debate.
But that's not the case. So if you want a small iDevice to fit in your pocket, that's what the iPhone is for (and you can make phone calls on it unlike with the iPad mini).
The only legitimate market for the iPad Mini is 16 year old girls. And not the smart ones who could stand to lose 20 pounds. I'm talking about the hot, bitchy, annoying ones with chihuahuas and little $2500 Kate Spade handbags. The iPad Mini will fit into one of those little purses perfectly. And whichever girl has the most expensive, shiniest, glitteriest pink Prada case for her iPad Mini will be the most popular among her peers - guaranteed head cheerleader and homecoming queen. I completely understand that. More power to her. Her parents would be horrible people if they didn't immediately buy her one.
But if you're not a 16 year old girl, and if you don't have a little $2k+ Kade Spade handbag in which to keep it, then you have no reason to get the iPad mini.
Lighter? We're talking 3/4 of a pound! That's it! You're bitching over 3/4 of a pound. That's practically the exact weight of a can of soda or beer. I bet everyone here has no problem lifting cans of beer up to their face every day. That's the weight difference between an iPad mini and an iPad 4. And you know what's even lighter than an iPad mini? An iPhone. It's cuter too.
