Isn't the SD card in the tablet partitioned, one for the system and apps and the other partition to act as storage of media?
A lot of tablets now do the SD card over nand as the price is substantially different, i think a 8GB microsd direct from factory is as cheap as $1-2 depending on class and manufacturer, whereas 8GB nand is still somewhere in the region of $8-$12 depending on time of the month and price fixing by Samsung and Hynix...haha. If we were to make a nationite tab i would also opt for SD card, its the same shit and in some cases the sd card has a faster rate of data transfer than standard nand.
A question on the firmware for other China brands, did they release the original firmware also for the tabs that run on Amlogic processors? If not then it could be some issue with the design house limiting the release of the base firmware that ships with the tabs, this would not really surprise me if it were the case, if not then Ainol are just being stupid and stubborn.
The sd over nand thing can be a good thing for most tablets, especially if you can get at it and switch it out...sadly the Tornados cant be opened up without destroying it, so it dosent fit in that category...but at least you get a choice of 8 or 16GB, and it still a steal at either price.
I've seen firmware released for the earlier versions of Amlogic tabs, but since Ainol seems to be the only ones with the newest ones that I have seen so far, its up to them to release the firmware that works on their tabs. These's no reason for not releasing your own firmware...its just plain stupid.At least Ainol have good to great after sale custom firmware's from some of the best developers out there...it's been their saving grace.
