The ferrari analogy was... just an analogy. With the right hardware and all, Android is speedy. I've seen the same phone perform very, very fast on other reviews - so in the end, it depends on the reviewer.
I've generally been happy with my HTC Desire, although a new phone doesn't do any harm but the thing I hate (yes, strong word) is the texting (in)ability without looking. I'm used to the nice, tactile-based numeric keypad.
