What we no longer have is convenient inexpensive
storage for modest
amounts of information, say a megabyte or two? Ideally, such a
medium would be read-mostly or write-once and a handful of them would
buy a cup of coffee at your local watering hole.
It depends.
- SD cards will be around for a long time - 10+ years
- SD cards were sold by billions. With B. So it is pretty easy to find one
at the wild, even at the poorest countries
- SDHC are rectroatively compatible with SD, so if you need a megabyte or
so, you CAN use a SDHC card in place of a SD card. Try it yourself if you
don~t believe me.
I still believe in market dominance by SD simplicity.
