Well that's rude. I wasn't arguing that anyone was building on anything. I was pointing out that arguing as such (like Sense UI being bad because it's "on top of" Android) is pointless. It seems like you got that point just fine.
My point is that it integrates into the low-level of the OS. It's not just a skin that loads up on top of the Android UI. It's actually an alternative. Much like using Ubuntu Linux and running either KDE or Gnome. It's not a downside.
It's a UI over an OS. iPhone OS is the same. It's a UI over an OS. It was a stretch to say Darwin, but you get the point.
Also, what does this have to do with specs at all? Totally irrelevant. Great deductive skills you have. Way to resort to childish flames.
Asking what it has to do with specs when you questioned if I knew what an OS was? I was addressing the mis-direction.
Having a discussion with you is pointless and circular. You have yet to address the spec point and your argument is flawed - you state Android's OS is polished yet point to the 3rd party overlays which in no way are the same thing as different flavors of linux. Windows Media Center would probably be a better comparison when running it on W7/WMC.
I'm genuinely sorry if my comments come off as rude, but your belief on Android's OS, in its current state, is solid is simply not true. Especially when you look towards HTC to "refine it..." Perhaps in a year or so. It's usable but very buggy as well.
