Just got a mini 6, replacing my mini 5. Overall, really like the form factor and the larger screen. Touch ID on the power button will take some getting used to, but overall, I really like this device.
Jelly scrolling is not an issue for me, I typically scroll very slowly when I am reading and there I do not see any jelly effect when I scroll this way. If I scroll very fast, and look for the effect, I can see it, but for me, it's not an issue.
Overall, glad with the purchase and I will be keeping this new mini.
