throw it out lol. u can either use a usb adapter, or plug in directly whatever the microsd is in (such as camera or cellphone). that thing they give u is useless

 

I had an extra microsd and no SD for my wii, so i used the microsd and the adapter for the wii. I say keep it just in case.

 

rly? i saw no noticeable difference...

well obviously it doesn't hurt to keep the adapter, but u have no real use for it. just put it sumwhere

 

My computer doesnt have that kind of reader, but anyways that USB reader that comes with my Cyclo works perfect and I can use it for just about anything.

 

Depends, for what flashcart did you get it from?
I would just keep it anyway as a backup or whatever. If you got the DSTT adapter, that might be worth throwing away.

 

I think you should hold on to it in case you might need to use it in the future. I mean, like most people have said, you can use it in devices such as cameras and laptops/any computer with an SD Reader, and even the Nintendo Wii and the Playstation 3 (older versions) can read SD cards, which expands the number of devices you can use the card on. Then again, if you absolutely don't need it, you could always recycle it somehow...? o.o
