have you heard of the saying of, "beauty is in the eyes of beholder"? I can tell you millions of people do NOT find what you said about win10 or even 8.1 ugly. There many things in life, SOME people find ugly, and some people find the same thing beautiful. In my experience in life, there are those who get use to something, and really don't like change of anything in life, when you give them something new and different, that they are not use to, they suddenly find something to complain about it and perhaps find it ugly in their eyes.
IMO, Windows 8.1 or 10 with LIVE tiles, are absolutely beautiful, and was ingenious design from day 1. I find it so cool that each tile is an icon AND a live informative tiles. Yes you can have a boring icon just sitting around, and then you have to click it to access its content that its been around for YEARS, but I and millions of people want something NEW and FRESH that is different and gives us the ability to just look at it, and see we should open it or not , with its live features.
With Win10 for phn, you get a wallpaper background of your choice(your dog, cat, friends, kids,......hot chick) and a live transparency tile over it, that's even better than Win8.1 Denim. How is that ugly???????????? Also, you can have a solid White or Black background if you wish. its 10x better than Android and 100x better than iOS junk toy. So please explain in detail as to why in YOUR eyes its ugly, when many people find it beautiful, clean and nice. thx
