SmartPhone sales are indeed impressive. And one certainty you can take to the bank: most of the people who have invested in SmartPhones are using them on a daily and/or continuous basis. They didn't shell out that jack just to tinker with them and then park them on a dusty shelf somewhere.
Even if you accept the frankly absurd claim of "3 million HD Radios sold," which I believe is inflated by at least a third, I would further opine very few of them are used regularly for digital radio listening.
Anecdotal evidence strongly indicates a huge proportion of HD Radios have been bought by first-adopter/curious hobbyists, radio industry professionals, and radio group owners and pubcasters for giveaways or pledge-drive premiums. And because of the glitchy operation of HD radios and transmitting equipment, I'm confident few are used regularly. (At WYSL we have an HD Radio - a Sony XDR-HD3 for off-air monitoring in ANALOG our FM translator. It has no digital application whatever - and there are hundreds of these receivers being similarly purposed by broadcasters.)
See the comment of DaveBayArea - a professional engineer. Not even he could reliably flog his balky, buggy HD Radios into reliable operation. When they were working, the programming wasn't there to justify the effort. THAT'S the story of HD Radio.
