I'll admit I stopped reading when I got to the part about the iPhone 4 losing 24 dB when held a certain way. How does the article reconcile 24 dB (a 250:1 power ratio, or a 16:1 ratio expressed in terms of voltage) with 38%? These are two vastly different values.
The Anandtech article only gives the straight-up dB (iPhone 4 loses up to 24.6 dB, Nexus One loses up to 17.7). The percentages I thought came from it as well but I can't find them now; I'm currently hunting for the article I'd seen them in.
At any rate, the question stands and I'll just rephrase it in terms of just the dB numbers: is 17.7 dB OK but 24.6 dB not? If so, on what basis? If not, where's the outrage over the Nexus One?
And that's without getting into questions like "is it OK to lose a bit more signal if the ability to keep functioning on reduced signal has improved enough?"
