IMHO, the Verizon iPhone commercial was MUCH better. It made the iPhone look sexy and desirable to the average person. I'm not sure the average person would even understand the XOOM commercial. Motorola just wasted a million bucks on air time.
Iphone is a well established product with 4+ years of A+ level marketing behind it. It has an official release date, pricing, and data plans.
The Xoom is the first product of it's kind, that's not using any previous branding (droid). It doesn't have a release date, doesn't have pricing or data plan info, and practically no one knows about it.
I'm still sticking that this is a teaser trailer, like the original DroidDoes commercial was. It shows you nothing, but it's a base they'll build on.
