Hmmm, let me comment this:
- For me, my home screen is the screen where I place those apps I frequently use. Not all of them. So it's not a busy mess for me.
- I agree, most of the apps do not need it. But, as I said, this won't cause my home screen look busy as hell, as there are only my favourite apps.
- I do not need to place my tiles so that they look nice. I place them in a way so I can reach them with my thumb. I'm right handed, so my frequently used apps are on the right side of my home Screen. Try this on an iPhone ... won't work.
- If you need to search for the app you want to open, you probably put to many of them on your home screen. Clean up your mess
- And yes, live tiles work on smaller screens. My parents, my parents in law (all of them over 70 years) and me use them. And we love them. I can stick a single contact to my home screen, and it's live tile will show me missed calls, mails ...
- Even a live tile in a subfolder works no matter how big it is
For me, the current version of the start menu in Windows 10 and also on my Windows Mobile Phone are the best I ever used (and I'd be an owner of an iPad and also an iPhone!).
