Chances are we'll go for a 16GB eMMC. Replace the number 200 with 16 in the above, or even 32. Does it still make sense?^ Not everyone is going to want 200GB of debian packages that don't even fit on a uSD card today and may never. As others have said, they have loaded debian with as little as 1GB . Only a small number of people are ever going to want 200GB of those packages, and as I said there is no guarantee uSD will advance enough to give you that anyway.
