I bought the iPad 3 when it came out. Biggest waste of money ever. I have an iPhone 4S and a MacBook Pro with Retina. Those do everything iPad does, and better. I gave the iPad to my mother and she uses it to read books. I'm glad it wasn't a total waste.
The iPad mini is the same thing but smaller. It's pretty cool but I have absolutely no use for it. Until they release a tablet that can replace my MBP with Retina, I don't see myself becoming a tablet user.
Not putting miles on your Ferrari is like not f*cking your girlfriend so she'll be more desirable to her next boyfriend.
