I just recently purchased both. Acekard 2i for my son and DSTwo for myself. Granted, I already have read all the topics regarding the comparison between the two and everyone talks about price points between the two and Acekard being the cheaper of the two. I rationalized DSTwo for myself only because I would or can see that I would play GBA games (probably, perhaps ) but the fact of the matter is, my son will just be on the 3DS. Did I make a good choice purchasing one of each? Money is not a concern for me because I would have paid 40 bucks for a game where I just invested it on a DSTwo. Anything I would regret with this? Both seems to be solid devices, I guess I wanted to have one of both to experience both... I guess if I purchased just two DStwo or Acekards 2i, I wouldn't have missed one over the other.
