Hello,
I'm using iPad mini with retina from january 2014 and i didn't encountered any problems since now. I'm a heavy user and streesed the hell out this device and got no crashes or problems.
I mainly use it with an apple keyboard and the experience is great.
The idea when i bought this tablet was to use it as a laptop replacement (i know it sounds ridiculous) but it worked great. With an app called splashtop 2 and a good connection to the internet i'm able to connect to my desktop at home and have a pretty powerfull machine at my disposal on the go.
Other than that... the battery life is great, with bluetooth activated non-stop, brightness always set atleast at 60% and almost always connected to my desktop at home it lasts all day with no problems.
So from my point of view this little piece of machinery is awesome and can take almost anything you throw at it.
