I too compared the transformer and the iconia in the store and pretty much agree on everything the OP said with the little exception of the difference in the screens being noticeable. Yes it's slight difference and setting full brightness makes it even slighter but still noticeable. The transformer's screen is by no means "miles ahead" as someone said but it's better. Certainly not enough to compensate for the USB port anyway.
