I also have an iPad mini, and when comparing this to that, I love the Samsung tab 4! It's comparable in size. I've only had it a week or so, but love it. The Google play apps are easier to download than off of itunes. The color and picture are so much better. Things just seem a little easier.
I am going to LOVE this tablet. I just got it as a gift and I'm in love with it. The size is perfect.. not too small but not bulky either. It's proving to be functional and easy to navigate. The display is awesome, and the apps included are very helpful. Going to finish setting it up then taking it with me everywhere.
