Randy: humm... i think all depends on the camera you have. if your camera shots pics about 3 Megs in size 256 megs are enough anyway... (so 128... ). But if you r camera shots are LARGE or even HUGE you can't keep exchange cards all the time. regarding SM durability. as all things they are durable if you keep a special attention on 'em. I'm only saying that there are solutions that are sturdier than Smart Media ones. only saying that i've seen a lot of Smart Media broken (almost for non careful usage) but no Compact Flashes. Anyway, if you don't mind that your support is 1mm large and you plan to be always really carful with your support , then i guess there's not a Smart Media support problem at all... Anyway i own several cards, from Compact flash to smart media and IBM microdrives for different use.
