I didn't actually mind the UI once I got used to it. If they had just made some things optional UI wise they would have been fine I think. I hated vista because of all the random things they changed for no real reason that I could understand. They fixed a lot of that with 7, but 8 was a jump too far. It made some sort of sense on touch screens, but given that most devices running windows at the time weren't touch screens it was problematic for long time users.

But around the same time they began pushing their hybrid surface devices and those all did have a touch screen so as a hardware decision I can still understand why they tried it.

I also kind of feel like it dumbed down a lot of the power user facing controls that most people coming from previous windows versions (especially XP) used pretty frequently. People talk a lot of trash about younger gens not being tech savvy and I feel like this is part of the reason. They couldn't tell you what control panel was, wouldn't know what to do with those settings if you told them, let alone using the run command to open msconfig, or the command line. They never had to do that because for them computers and phones just work (most of the time).

It's frustrating the number of things I feel like Microsoft could have done to make 8 better that didn't involved the adpocalypse nightmare that they have become with both 10 and especially 11.
