Palm m500/m505 - SD expansion cards and MMC expansion cards

I hope this is the right forum for this, but I was reading up on the m500 and the m505 and was considering buying it. I was wondering what the difference is between the SD expansion cards against the MMC expansion cards. Do they function the same? Are they both rewritable? On egay, it looks like the MMC expansion cards are a lot cheaper... why? Do they both essentially work the same, and if so, why did Palm make their first 16mb expansion card in SD format (there's gotta be something better about this type of card)? Would you suggest buying against a non-Palm brand expansion card, because those egay 64mb ones look mighty tempting.

And most importantly, if I were to buy either one of these cards, could I fill them with mp3s or some type of audio file(s) and play it on my palm without having to buy additional hardware/software.

Thanks in advance to anyone who helps out. 🙂
 
From Palm.com:

Tiny cards pack lots of data.
If you've seen the new Palm? m500 and m505 handhelds, you might be curious about those little slots that hold postage-stamp sized cards. Here's the story that proves big things come in small packages.

What's behind the expansion card slot?
The expansion card slot is a dual-purpose slot that can hold two types of cards: Secure Digital and MultiMediaCard. Both types of cards are small, inexpensive, and easy to plug in. Much like computer diskettes, they hold information for upload or download onto a handheld. With them, you can instantly add software programs, e-books, large databases, graphics, or even video files to your handheld without sacrificing memory space.

Both types of cards are widely supported by hundreds of consumer electronics companies, and are used in many different devices including cameras, video recorders, MP3 players and much more. Palm chose to support both types of cards so Palm handheld users and developers would have multiple expansion options.

What does the future hold?
Right now, there are hundreds of hardware expansion products for Palm handhelds including digital cameras, GPS receivers, wireless modems, scanners and more. In the near future, Secure Digital Input/Output technology will enable the same functionality to be delivered in an ultra-compact size on an SD card.
