Why isn't there a 16 GB Fuze?

"But mostly I figure it doesn’t matter "

 I disagree. Most women, even if they use plenty of high tech gear, don’t like to talk about it. I have always wondered why that is the case. I would love to have a wife who would like discussing high tech stuff(I am single).

“Back to topic… I just put more on my 8gb card and need more room! ( Yes I know, I should have just bought the 16gb card…) my internal memory is full too…” 

It seems difficult to find reasonably priced brand name class 6  16 GB micro SDHC cards. I don’t recall seeing any 16 GB micro SDHC cards by Sandisk faster than class 2. I guess class 2 is okay if you don’t change your  music much. Is my math correct? Can it take over 2 hours to fill an empty 16 GB class 2 card?
