instead of 3GB of RAM and 64GB of storage
Is the 64GB storage correct for the earlier Librem 5 USA? I thought that it was the same as the Librem 5 (non USA) i.e. 32 GB - but on no evidence, since I don’t own a Librem 5 USA.
support for WiFi 4 and Bluetooth 4
This is definitely wrong unless the SparkLAN card is not available with the Librem 5 USA.
But, yes, the price of the Librem 5 USA is not determined by the specs. See also: Introducing the Liberty Phone
I would think so. Hence why the RAM can only go to 4 GB.
