I might buy it.
Why? I have an iPhone but its functional but not a lot to study or read PDF's. My dad has an iPad, its great for reading PDF's but it's too big.
I will use this iPad Mini to study, watch documents in a comfortable way (for me), i will download apps that *** I already bought over the last years and because i know how to use each app*** , i will use my iPhone 4 for calling, emails & MP3.
My iPad Mini would be my "documents reader", videogame console ( GTA 3, Infinity Blade, etc) and to take notes.
So yep, it's great for people like me that thinks the iPad it's too big and the iPhone is good but not great for playing or reading big documents. ( i want it for calling and emergencies) and mostly because i already invested a lot at the App Store over years.
Now i hope it's good and it's cheap.
