I bought the white retina iPad mini (wifi-only) with 128GB storage. I purchased it at the Best Buy online store on the day after Christmas and got it in the mail by January 6th - a few hours after I got my rMBP in the mail!
At first, I never thought I would own an iPad because I didn't like how big the originals were. After I put my order for my rMBP on Christmas Day, I was looking through the Apple site and by chance noticed that they had the retina version of the mini! Perfect time to get myself an iPad (since all my apple devices that I have are retina anyway - iPhone and rMBP, why not complete the set?).
I ordered it the next day because I had to think it over, and once I woke up, my decision was made. I originally wanted the retina iPad mini solely for the purpose of using it as an e-reader. Prior to this, I was reading books through the iBooks app on my iPhone and I purchased a LOT of books, so it got me thinking. I wanted an e-reader, but I didn't want to have to buy the books all over again because it accumulated a lot of money over the months, so I figured, get the retina iPad mini.
It's the perfect device for reading; the size is perfect, the screen is amazing, it's light - just everything about it fits my needs for it perfectly. The only reason why I purchased the highest storage available (as expensive as it was, especially after having made a $3500 purchase the day before) is simply for the fact that, apart from my rMBP, it will be my go to device for gaming, watching videos/movies (like Netflix, YouTube, and the movies I have stored in the videos app), reading, etc. I absolutely love this device. I don't regret purchasing it, and above all, I haven't noticed any of the problems that other rMini users have reported such as image retention, yellow tint, etc.
Everything about my rMini is perfect and has been since I first opened it from the box. The rMBP and the rMini were both late Christmas presents for myself and it's by far the BEST Christmas gift I've ever received!!
