Amazing piece of engineering, but I'll be holding out for the 128Gb version of their Cruser Fit as it protrudes less that a standard SD card adapter on my 2011 Air.
Haven't had much luck with microSD cards: I once bricked a 32Gb card after knocking the SD adapter again a chain arm on a train and had a failing 4Gb card get so hot it melt the provided USB adapter.
