Compulab EM-X270 Wireless PDA Module

Hi all,
we all love choice and openness.

Currently, there is only the GTA01 available for OpenMoko and the  
GTA02 still needs some time. This has raised the search for  
alternatives. Especially the Wireless PDA module EM-X270 from  
Compulabs was discussed positively - except for its missing  
availability to single individuals.

Therefore, we have decided to start a Group Purchase. The target is  
to reach 100 ordered units so that the price remains reasonable for  

Well, it *is* more expensive than a GTA02 will be. It *is* more  
expensive than an iPhone (subsidized). But it is superior in some  
(not all) aspects, quite open and you can install Angstrom Linux.

Group Purchase:

Please don't be scared to death by our price of EUR 649,- compared to  
the $122 written in the data sheet. We can't do magical cloning or  
beaming of hardware (only with open source software :-).

First of all, the $122 is the naked board with minimum memory and CPU  
clock, no display, no battery, no keyboard, no GPS, no GPRS, etc. We  
have choosen to bet on the most powerful version (so that it is still  
a competitive device in 2-3 years). Next, Compulab has a multiplier  
factor for orders below 1k units. Finally, this price includes all  
our handling, shipment from the manufacturer to our stock, some  
import duties, warranties, risk reserve funds, stock management and  
handling cost, credit card processing cost, etc. And finally some  
compensation for the time we spend doing this instead of other  
things. The largest single cost component is the German VAT of 19%.  
If you are ordering from outside Germany there are options that we  
ship with no VAT (i.e. 545,38 EUR).

So, our target is to reach 100 ordered units by end of January 2008.  
You can help to get choice into the OpenMoko world by either ordering  
a Compulab Module or at least spreading this information and  
directing those who are interested to us.

One more thing ...

... if Angstrom works, OpenMoko should also work with some  
adaptations. And QuantumSTEP as well.
