I used windows 8 for a year now on my Sony Vaio laptop ;) and there were always a few shortcomings however I didn't really had a problem with the operating system. It was fast, had a few nice apps though I mainly used the regular desktop after a while. Now with Windows 8.1 I discovered a non-advertised feature that actually is my favorite one too.
Whenever connecting my laptop to my Bravia television it recognises everything in W8 and I use my android phone as a remote. However the desktop wasn't really made for television and that caused for irritating browsing in files and chrome. However W8.1 is automatically scaling all windows and also the start menu which makes using the OS on television much easier. Such a small thing made me really love the new update, especially since I use it a lot on my television.
What is your favorite feature in W8.1 and what kind of changes do you want to see?
