I am not sure why the debate over SD cards continues but this should finally put an end to that:

Yep, 128GB for $155. Just over $1 per GB. Added to the built-in 64GB this would give you 192GB. Plus you can have two or three of them and swap them as needed. There is nothing left to debate, SDHC is a must have feature.
