New MBAs only have SDHC not SDXC

Yep, kinda disappointing they didn't add that when every single other recently released Mac has it (even Mac Mini).

Just another reason the MBA is always a few steps behind... Doesn't make it feel very premium. It's a shame because it shines so well in other areas (weight, SSDs, lack of ODD, etc.)

On the plus side, at least it upgraded to Bluetooth 4.0 and returned to backlit keyboard.

The Oct 2010 Macbook Air's do support SDXC but not at the advertised SDXC speeds. I'd hazard a guess nothing's changed.
