I don't in any way discount your experience or rating of OpenMoko; I just base my assessment of the usability of the platform on the totality of the public reviews -- which, regrettably, are on the negative side. Like I said in the article, I have a ton of respect for what the project set out to do.
In my personal opinion, the real distinguishing characteristic of it was always the open specs for the components, it wasn't the shine of the software. But they did choose to pursue writing the OS and designing the hardware device from scratch, which might have been too much. Given the company's troubles, I don't think the future looks particularly bright for the project, but hey, maybe it will turn out okay after all. I follow it closely; we'll see where it heads. In the meantime, though, the evaluation of the masses is that it isn't ready for prime-time, non-hacker usage. Still, if you like it, that's great. It's good ot have options.
