Hey, SD cards are SD cards. That's why they're called a STANDARD. Anyway, the part about 'Designed for palm handhelds' is simply a marketing thing to sell more cards.
From a marleting perspective, it's easier to make a sale if people had the reassurance that a certain product worked wth their gear.
However, it's quite well-known that SANDisk cards plain suck. In my experience and that of many others in my user group (PPCSG), it's slower, more unreliable, and has less space (due to the UNIQUE way that SANDisk measures their bytes), among other not-so-positive comments.
