@panpan: Looking at the memory and storage specifications for both the original Slate (AR750s) and the Slate Plus (A1300), I noticed that the new model has twice the RAM memory, the same amount of NAND Flash, but only 1/4 the amount of NOR Flash. Is this correct? With only 4MB of NOR Flash I do not think it will be possible to load OpenWRT into NOR, so we really will only have NAND Flash to work with.

AR750s :  DDR2  128MB / NOR Flash 16MB + NAND Flash 128MB
A1300  :  DDR3L 256MB / NOR Flash 4MB  + NAND Flash 128MB
