Those who have a 4.4 kitkat device- how you finding it?

My battery has been a lot better since 4.4 on the 2012 nexus 7. Other than that don't see much difference in anything else

Finding battery improvements as well, not sure of its kit kat, ART, or both - but it is noticeable. I haven't even tried kit kat with dalvik, very stoked with ART.

In KitKat it's experimental or beta (thus in developer options, for developers), so unless you're a power user, it's not recommended that you enable it.

Well that doesnt explain much. I still dont know exactly what it does.

What if any apps have been broken using ART?

I haven't tried many of mine but did discover Slingplayer doesn't work using ART. I use it quite a bit so I've switched back to Dalvik.

Thought I read somewhere that Whatsapp also doesn't work using ART, but I don't personally use it, so don't quote me on that.

Certainly some, but none that I use/need.

Androidruntime.com has a great compatibility search/list

Whatsapp is probably the biggest name app that doesn't work.

4.4 kitkat is not a huge update, but from what i've been told it lays the ground work for the next os version which is suppose to be a major update.
But everything is just speculation at this point

I astonishingly got 13 hours of battery life and 3 hours of on screen time today on my Nexus 4.

That's why it's in Developer Options (which have to be unlocked). It's not for casual users. If you don't understand then you shouldn't be using it - as again, it's beta/experimental.
