I'll put it this way: The iPad would not be a compelling device if it merely ran iPhone software at a higher resolution.
Hardware-wise, the iPad is nothing but an iPod Touch with a giant screen and a giant battery. Software-wise, it's everything but an iPod or iPhone; the use cases are very different. A touch-surface that's 5 times larger than an iPhone enables a much richer and more sophisticated UI, and this is evident in the iPad SDK, Apple's iPad software, and the successful 3rd-party iPad software.
Google needs to define their tablet HIG, they need to update their SDK to implement their HIG, they need to update their built-in apps to take advantage of the new SDK, and they need to get their 3rd party developers on board. All of this takes time, and I would not expect it to take shape before the spring or summer of 2011 (they're still "feverishly working" to get Android 2.2 out the door). Anything less will result in a product that's not as compelling as the iPad.
That said, I have no doubt that manufacturers will try to sell Android tablets before the Android OS is ready, and I have every confidence that those tablets will fail in the marketplace. But eventually there will be compelling Android tablets.
The linked article, and you, seem to be suggesting that Google needs to add capabilities to Android to support different resolutions and pixel densities. I'm saying that they already have. In fact they're already talking about developing Android apps for Google TV, a 3rd entirely different form factor.
Having to update Android apps to take full advantage of newer form factors, is entirely different from having to fix Android itself to work with different form factors, and even if the apps are not updated they'll probably still generally work better than iPhone apps on iPads because of Android's inherent multiplicity of devices.
