This is why you see micro sd cards going on sale every few weeks. Although I've yet to see Samsung's prices dip (as much) as it's mainly the off brands or Sandisk that cuts their prices first and most often.
Will we see mass production of 128gb micro sdxc cards this year??? Huh?
Licensing sdxc for tablets & smart phones would be a good idea too! Until these happen, this would be a niche market because the data rates by sdhc card slots are too slow even though they are compatible with sdxc.
SDXC cards start at class 1 (overlapping with class 10 on backwards compatible sdhc) and will go upward from there...
