I tried the Rodriguez MIUI ROM today after being wowed by the videos I saw on the internet, but in the end I've decided its not for me.
I think its partially because coming from an iphone, I've become accustomed to the android way now, yet for me, its does seem to be trying to ape iOS somewhat... and yet despite the talk of it being blazing fast, the reality for me is it really didn't feel as snappy and smooth as I expected, and I didn't really enjoy using it, so it lasted all of a couple of hours.
I do appreciate what they've done, and it goes to show what's possible, but in the end I went with CM6 and the Minimalist Matte theme, and find my phone actually smoother and more responsive with this, and a decent Quadrant of 1405 is good enough for me - but in the real world the phone is really fast and snappy, which it didn't quite seem with MIUI.
So while I do admire what they've tried to do, and to a large extent, achieved, it just felt too much like a poor mans iphone for me, and hence, felt it wasn't for me. It's good to have choices like this though
