that would be the case if they released it for the DS but all he's doing is filling a gap the iPhone desperately needed filled and for that I applaud him.
Although I know of at least one other game for the iphone which seems quite similar (though hex-based) in quality, I understand what you mean. But I, personally, am less interested in a game like this when it is so obviously nearly the same as another one I've already played.
Still, like I said, I can understand that someone wants to have "Advance Wars on iPhone", and I guess at such a low price point and seemingly good polish there's hardly reason to argue against that
