All of those, besides perhaps the Droid and Nexus, are highly constrained, while Erises are probably easy to get by raiding the dumpsters behind Verizon Wireless stores of all of the audio bug phones that Eris customers have returned.
I assume that they chose a Verizon phone with a fairly weak radio for a very strategic reason, vis-a-vis a comparison to an AT&T phone.
Perspective here, people. Apple has offered not only a free solution to the problem - a free case - but also offered to refund the purchase price for a full three months. What has Verizon Wireless and HTC offered to Eris owners with the silent audio bug? Another Eris, which may very well have the problem? Certainly not their money back. In fact, perhaps Apple should have researched these forums and reported the crap that Eris users have had to go through with the silent audio bug, never mind antenna attenuation when held in the wrong way.
Last I heard, they were giving people refurbs, new phones, and even letting them upgrade because of these issues. Which, btw, don't seem to be near as wide spread as the iPhone 4's. Consumer reports was able to duplicate the issue in EVERY phone they tested. It's how it's designed, not some random thing like the silent bug. Verizon is working on getting a fix for it. I give them a lot of credit for all the MR's they've given us, plus a new OS upgrade.
I don't know more than a handful of people IRL with an iPhone 4, but all of them seem to report either no antenna problem, or noticed a minimal problem, but have reported that the 4 is much better at holding a call than a 3G or 3Gs, and have absolutely no interest in trading them in.
Because they're lucky enough to be in a "sweet spot" of reception. But others aren't so lucky...
(I count myself as one of those lucky Eris users who never had the silent audio problem, very thankfully. I'd have hated to go through that crap. I'm also hoping, for everyone's sake, that the update coming out tonight fixes that bug once and for all.)
Amen. I really feel bad for those on here who seem to be cursed. But I really don't think they're the majority.
