So what is the concurence, and why Pyra Mobile is better? I noticed Neo900 and GPD Win.  
Neo900 is going to  have small support and I want  bigger device. N900 on which Neo900 is based, almost  lost support 

GPD Win can use Win10 out of the box - cool, can have linux as second system - cool, but it can't work as a phone.
So best pick seems to be Pyra Mobile, but there it seems to be more costfull than the concuring devices, but perhaps it's with a reason. 
First I thought the  reason is that startin production was extremely costful so the  big price was to feed the budget and pay the debts.
Recently I hear from you that it's not the  case and the hidden costs were much smaller, as used hardware itself is costly, so makes me sad.
I don't want  to hunt on EvilDragon's wallet and Pyra Mobile at once, he  deserves big amount  of money for making Pyra alive, but  I hoped that, it could be cheaper a bit...
@ClockworCoder do suppose think there would be better CPU board in 6months? it  not  neccessary have  to be done from scratch. If it would get 64bit or PAE and have at least 8GB of RAM (or preferably 16GB version) I would buy it almost without considering "yes or not" even if price would go a bit higher (since it would have  4x memory, new  tech CPU and probably faster).
