Info:
A new M3 Slot-1 Solution for the DS/DS-L is coming soon

The M3 team has been very good with its older products, so I trust this one to be just as good. You'll need MicroSD which isn't that expensive. Also it'll be nice to have a drag and drop system instead of the M3 Manager. Lets hope the UI is pretty too :P
