You can't not see the jelly scroll (unless you only use it in landscape). You're just choosing to ignore that it exists to justify your $500+ purchase.
Not everybody notices these things, just as some don't notice or care about flickering and color uniformity issues (which to me is way more important than jelly scrolling), heck some people don't even notice dead pixels. Jelly scroll is factually there, nobody is denying it. Through this I recently discovered my Pro 11's jelly scroll which I've had for soon-to-be 4 years, so it definitely can go unnoticed. Apple certainly cheaped out on the mini display.
That being said, I acknowledge it's there and also acknowledge there is no other tablet that can replace how perfect the mini's form factor is (for my use). For me to notice it I have to fixate on the way text shifts when rapidly scrolling, which is not a dealbreaker for me, but it may be to you.
