Is the 16GB SD card limit a limit of the hardware or the software?Could we potentially use something bigger in the future with an update of some sort? Or are we stuck with 16GB because that is all that existed when this device was constructed?Also, what brands/models of SDHC cards have you peeps had success with? Does the class matter?(I would love some newegg links=)Just trying to get all my ducks in a row while I patiently(ok, so not so patiently) await my A81E's arrival!Great forum btw. Very informative.
