I really like the direction that the DS-X is going in. DSLink's microSD is cool, but I don't want to flash. I also really like how you just plug the DS-X directly into your comp, much like my G6, though the G6 doesn't come with the USB extension cable it really requires.
My G6 Lite treats me nicely and I don't have too many regrets about buying it. The only thing that would kinda make me mad would be a:
- Slot 1 flashcart
- 1GB or more of storage (removeable or not)
- Doesn't require you to flash your DS
- Runs GBA games/homebrew
Throw a skinnable interface on that and I would consider replacing my G6 Lite, assuming that game/homebrew compatibility is high.
