Got no reason to back-pedal! Just strikes me as rather pedantic to be honest.
Not really bothered
I fail to see the reason for even naming a brand to begin with. SD stands for Secure Digital. It is a specification for accessing NAND flash based memory cards. eMMC is a close cousin, which stands for embedded multi-media card. SD evolved from MMC. Really, SD is just MMC, with some ecryption and locking stuff, (and in later versions, some additional IO modes, bigger LBA registers, etc) added.
Personally, since the eMMC module of the NX is basically just a naked passthrough breakout board, I would like to see a microSD to eMMC adapter for the NX. (Replaces the built-in eMMC module completely-- breaks out a microSD card slot instead.) Then I could put a 400gb module in if I really wanted to, using COTS parts, at the expense of being slower, and less durable (write life wise.)
