Working for a large organization, I get people in here with all different kinds of digicams and a million different types of memory cards. Lemme rattle 'em off for ya. Secure Digital Multi Media Cards Smart Media Cards Compact Flash 1 Compact Flash 2 IBM Micro Drive Memory Stick Memory Stick Magic Gate Memory Stick Pro xD Pictures Card PC Cards AAAAAAARGH. And there isn't a single drive on the market yet that will read every one. Some company called Dazzle says they are putting one on the market in a month or so that will read every format. That'll be nice. My biggest beef is with Sony. If SD cards can be made with 512 to 1 gig capacity and not require new drivers or new hardware to read them, then Sony probably can do it too. But they don't .The new memory stick Pro's require new drivers and adaptors/readers. Sony is a money grubbing machine who make their technology different than anyone elses just so they can make more money off the patent, and it is a total swindle of the consumer. Anyhoo, while I'm on the subject. Can anyone here tell me where I can buy Secure Digital cards for cheap? Looking for 512 Mb to be specific.
