Yes it is. Very much so. Android still suffers from the dreaded lock phone call (wherein your phone is ringing but it wont let you answer). To understand why, you have to understand the method in which the operating system works, or rather the UI layer because the true operating system is linux which then has to deal with virtualizing the Android OS.
Even Windows Phone does a better job at this than Android which is why a cheap Windows Phone with 512 MB runs smoother than a high end Android. I'm not knocking Android here per se. I'm no Windows fan boy nor iphone fan boy, but the truth is the truth. Android has a NUMBER of knocks against it. The VM, the UI and lets not mention Java itself which inherently is slower than a true native device.
In fact the only reason its gotten better is because the hardware has gotten that much better; the OS itself still has a ways to go.
