The thing with iPad Mini is, that it feels so personal, like a journal.
I'm already back into writing diary with this one and the DayOne app. I'm reading magazines like Edge with no trouble. I'm handling Pages documents for my economy and applications and oh wow Bastion looks magnificent on this little device. I'm also reading books in Kindle, keeping everything in check with Calendar and watching Netflix in bed with the Smart Cover supporting it fine.
I could do all these things with the big iPad but with this form factor, size and weight - it all becomes more personal, something closer to you, something of meaning. Beautiful.
Besides, it still got battery since yesterday morning and I used it all day yesterday.
