Is that why you're going to iOS? I mean, as opposed to having something against Android? Are you actually
switching to Apple, or will you use it and Android both?
Personally, I could not, would not, accept the locked-down, non-customizable, highly-curated world of iOS. Just the thought of having a screen-full of icons--that I didn't put there and don't want--makes my heart start racing, like a panic attack!

I need my desktops clean, not all cluttered up with stuff I can't remove.
I'm interested to know why you're doing this, but as it's none of my business, you're certainly not obligated to explain.
