Now, I'm not of that opinion at all. Even a cursory examination of the Open Handset Alliance membership list indicates that you've got a bunch of companies with technology expertise so wide-ranging, it's impossible that their cooperation wouldn't yield a GPhone. To put it another way, throw a bunch of engineers from these vendors into a room, and a week later out would pop the best smartphone the industry has ever seen. (Or the most bloated, if no one steps up to the plate to adjudicate feature-creep.)
My assumption that Gphone efforts are already in progress stems as much from one key factor as from all the other minor evidence combined. Namely, a couple of companies with software-integration and training expertise are involved. You never need those folks -- and certainly no one wants to pay them - unless you're looking to bring a project in for a landing.
I'm not terribly familiar with Noser, so it's hard to say for sure whether it's got a serious role in GPhone. But it certainly seems to be the company you'd call on for serious software testing and integration. That's the phase of the project where the operating system, apps, and hardware are buzzed out to ensure that everything works properly.
This is where Wind River might also come into the equation. The company is largely known as a vendor of real-time operating systems and development tools. (Those who've followed the embedded arena like I have give Wind River lots of credit for reinventing itself in the twenty-first century, after a long touch patch, as customers moved away from proprietary RTOSes toward open-source code.)
However, a company like Wind River doesn't simply throw its products over the fence to customers. It's able (or was in the past) to offer deep technical assistance, including help on the project management and software-integration fronts. I'm thinking that it might assume such roles in the Android ecosystem.
Finally, the broad range of semiconductor and service partners in the Open-Handset Alliance, as well as the membership of Taiwanese handset make HTC Corp., give additional impetus to the idea that a GPhone is in the works.
Heck, one member of Google's alliance -- HTC Corp. of Taiwan -- is all by itself the big sleeper in the smartphone market. It makes phones as interesting as anything from Apple or RIM (my personal favorite).Take the HTC Touch. You could slap a new wrapper and some software on that baby, and you'd have something you could call a Google Phone tomorrow. The only reason HTC isn't on the consumer mass-market radar screen is that it's in Taiwan, both physically and culturally, so it's off the beaten "brand-awareness" path. Also, it's spent much of the time since it was founded in 1997 making Windows Mobile-based Smartphones.
So keep an eye on HTC and watch for GPhones sooner rather than later. (The full list of GPhone, oops, Open Handset Alliance, partners is here.
