I'm an American, and I'm a geek; and I couldn't agree with you more. I've had a Nokia 5800 for a bit less than a year, and it constantly blows me away at how much more useful it is, and at a price so much less than other popular options.
I don't watch TV much at all, but the amount of advertising for the iPhone, and, now, Android, is rather extreme. Nokia, comparatively, is nowhere to be seen. I'm personally OK with this, as I think everyone is a bit flooded with adverts regardless of the genre; though it certainly does infiltrate the consciousness of the population who go out and buy mobile devices.
The second trouble in the US is the trouble between Nokia and the US carriers. Verizon firmwares are very much standardized, tending towards Verizon services; and likewise for AT&T and the others. They're developing their brand heavily, infusing it into the devices that are subsidized. In a sense, it's a constant advert for the device itself.
However, with the advent of the iPhone, along with its AT&T exclusivity, there are now subtle breaks from this pattern: iPhone implies AT&T, and so boosting the iPhone brand also boosts AT&T. Android is similarly a bit more independent, and the red markings are aligned with Verizon's brand go hand in hand. The "droid does" campaign boosts not just Android, but Verizon, since it's exclusive to this carrier. Of course, the only way that either of these cases work is with a massive amount of advertising in the devices themselves; again, something that Nokia does not exert in anywhere near the same force.
Personally, I find this all to be a good thing, for me; I don't particularly like the saturation of advertising, and part of the value of the Nokia brand is that it isn't being shoved down my throat. I picked up my 5800 for $260 after rebate, unlocked, with no carrier obligations. My data plan is half the rate of other branded, carrier-subsidized devices. Now, especially with Ovi Maps for free, it's just an insane amount of value, well above anything that's offered in the USA otherwise. A friend of mine has a Droid (Motorola Milestone), and, sure, it's a nice device; but I get more battery life out of my 5800, and there's really nothing that I feel is lacking from his general mobile experience to mine.
The sad end result is that marketing works. Even so, the worst part is that, as Steve mentions, the American tech journalists continually forget about financial restraints. They most all seem to be caught up by a cohesive mega-cool bubble which ought not be popped by an average person's income. I find it very irresponsible on their part, especially when there are so many people without jobs or money or both. That's not to say that there aren't a lot of wonderful devices out there; but that _especially_ in these financial times, the lower end of the graph deserves more attention, not less. At the end of the day, it's about access, not image, and I appreciate your continued fight towards that end.
