My phone and Nook Color are both running CyanogenMod 7, which essentially amounts to stock Android 2.3.3/2.3.4 with tweaks. I do not think they could look more different from iOS. Where is this "resemblance" theory coming from?
EDIT: By "tweaks" I mean "under the hood", as far as I can tell.
That is why Metro is such a breath of fresh air. If it came from Apple everyone here would be praising Apple for breaking the status quo, being the UI disruptor, etc. etc.
