Hello,
I see that Luke's friends/rivals at Olimex are considering the idea of a laptop based on their "64-bit" development board:
More on it at http://www.cnx-software.com/2015/11/10/allwinner-a64-datasheet-and-user-manu...
KiCAD design of the schematic is available along with datasheets.
Reading the datasheet, the device is capable of addressing 3GB RAM, though I am not sure any performance improvements are gained because the L1 cache is only 32k :(
With 64 bit words to chew, the cache is only about 4K words. Down from the 8K words in a 32 bit ARM :( :( :(
Still, the graphics ought to be quicker with the hardware present in the chip and ability to move data in larger chunks.
