So far, here is what I think the SD card can be used for:
- Saved Games
- VC Games (but I don't think you can take them and play on a friends Wii)
- MP3 Music
Did I miss anything?
I'd like to use it for the following:
- VC Games (be able to take to a buddies house and play)
- Mii's (Take them to my friends house)
So far, I only have 80+ photos on my 2gb SD card. I use the slideshow feature to show photos off. I like how FAST it works. Once in a while, I'll doodle on a photo and send it to my brother and nephew.
