You are completely right in your expectation that we share. We would  
be happier if we could offer a motherboard replacement for the  
Freerunner. With OMAP and UMTS. But as Werner has already found out in  
the GTA02-core project this is still very far from becoming reality.  
The complexity is balancing circuit design with availability and cost  
of chips, and pcb layout with production processes.

Nevertheless, the great open source mobile phone software developed by  
this community (SHR, QtMoko, FSO etc.) needs to have modern open and  
documented hardware to keep pace with pretededly-open platforms like  
iPhone, WebOS, etc. Therefore, this Openmoko Beagle Hybrid board gives  
us a tool to develop mobile applications with state of the art  
performance (except form factor).

We, a small team of hardware developers, will continue to work on  
integrating everything better - but this is a long way to go. I am  
sure we will finally succeed because we have decided to do so, but I  
don't know when.

So it is better to have something suboptimal than nothing...
