"It's a bit faster, there are some other minor obscure improvements, and if you just ignore all of the crappy new stuff it's not a big deal!"

If boot times are a big issue for you, then I get it. For me, they aren't, so I'm inclined to pass on the update. Perhaps it would work great with a Windows Phone or Surface (I'm tempted to try those at some point, so if anybody would like to share their experiences with theirs...), but it doesn't seem like it was designed for a desktop. So why should I put it on my desktop?
