@YoDude: Yes. If I were them, I'd prefer to have a bunch of HUGELY PROFITABLE one trick ponies. This way they occupy unique market spaces and will have little chance of muddling each other.

I'm not sure what sweet spot you're talking about, as it hasn't struck any chords with the market except for a niche developer crowd that only seems to care to develop for their own need. Why would Nokia want to cater to them or listen to their suggestions if all they care about is themselves?

Re: tetherable bt wifi donglicious thingamajig: yes, that's what you want. I want them too, but you should think from their point of view to see the viability of such device and how to properly market it.

Ink jet cartridges..? really?
Have you compared the prices for iphone apps with other commercial mobile platforms (palm, blackberry, winmo\winpho)? I think they're the cheapest around and they've managed to do this because of the sheer quantity and the rather efficient AppStore.

Commoditization of the products can only happen when the market is big enough and knowledgeable enough to piece them apart... and if there's enough saving by going with that route. Right now it's 0 out 3.
