So, like a lot of people starting Android development with Eclipse, even with a fast machine, I notice that the emulator runs frustratingly slow.

I have the same problem occasionally, and I'm unable to tell you exactly why this problem occurs, but it seems that the AVD won't start if it has been allocated more then an X percentage of your available RAM at the time of starting.
If you lower the given amount by just 50mb, you'll often notice it will run just fine. Or, similarly, if you close a few programs to save some RAM, it will also boot up perfectly fine.
I know it's not ideal, but I suggest to just lower the allocated RAM in small amounts until it boots up. I wish I could give a better answer but I haven't been able to find a reason myself either.
