I expect my GateWay to come in within the next few days, and am going to get a microSD card for it in the mean time. After reading, some users have been reporting issues with their GateWay due to slow cards, and a guide on 3ds-flashcard.com said that the 16gb Class 10 Kingston card is not compatible. Now, about these people that are using these 'slow' cards. Are they referring to cards that are less than class 4? It seems that the 8gb Kingston Class 4 card is the most popular choice. That being said, which microSD cards are 'not compatible' with the GateWay. I would assume all micro SDHC cards would work, but the statement on 3ds-flashcard.com makes me hold back on that assumption. Second, would there be such a thing as too high of a class? Could I have a class 10 card work okay with it? Lastly, which card would you guys recommend? Thanks!
