I think he would say: Snapdragon.
There's a lot of hub-bub about the processor, but Qualcomm stated only a 5% improvement compared to OMAP. Either way, it's an improvement. Sense UI ROM will be available once it works without a hitch with 2.x. But that's the current hurdle for this phone is Sense UI stability on OS2.x. But that's the beauty of Open platforms. There will be something better. Someone will come up with an alternative home interface. Other than the HTC phones, the Droid phones are a "blank canvas" so to speak and any UI ROM can be layered on top.
