Which fanboys are you referring to? The apple fanboys, maemo fanboys, android fanboys, Jolla fanboys, N9 fanboys, windows fanboys? Wait... are there windows fanboys? I dunno...

The difference between Dalvik and ART is that Dalvik's layer is generated during runtime of the application and ART pre-generates whole right after installing the app.
The level of indirection stays the same - only app startup/wormup time improves.

Maybe I'm confusing things by using the term layer although some times I see diagrams with Dalvik between the software and the CPU. I suppose ART would be there but used differently. I think one important difference is how ART and Dalvik handle the compilation of apps. Because ART uses Ahead-of-TIme (AOT) compilation there can be significant improvement of app performance over Dalvik which uses Just-in-Time(JIT) that compiles code when you run the app. AOT compiles code when you install it.
Maybe JIT approach was useful to reduce memory usage but at the cost of performance speed.

I have been using ART on all my android devices, it makes a noticeable difference in performance and battery life.
From what I read up on how it works, the uncompiled apps are put on the play store, and the device locally compiles it, and then runs the compiled file, as opposed to interpreting it as it goes. The only issue I have had with ART is 2 seconds of lag when the file is being compiled.

Unfortunately on the Galaxy Note 3 that I have, ART isn't an option. Samsung didn't include it.
I really wanted to see the difference it made.
Granted, I could probably try to find a more standard ROM for my phone, but then I would lose all the cool stylus functionality, which is the main reason I got the Note 3.

Agreed.
I'm on Alliance ROM for this reason. All the benefits of TW ROM, but more lean and much added functionality from AOSP ROMs. ART isn't even Xposed-compatible...yet.
I do wonder if ART has a more noticeable impact on slower devices or faster devices.

Has anyone tried making a cell phone using raspberry pi?
