ok, but the initial system (kernel) etc. should boot from internal 
flash, only data/big packages should be on SD

flashing a new image is as easy as:

scp image openwrtbox:
ssh openwrtbox
sysupgrade image

that is not true. the product is intended to be flashed,
it comes with SDK and linux, so there is no loosing of warranty.

it is riskier to flash on SD (it's NAND) than to use NOR-Flash 
(builtin). NOR has no bit-errors, but NAND has - thats the reason
for cheap USB-sticks.

This is the reason to have the bootloader/kernel etc. on NOR.
