Honestly, this strikes me as nothing more than a lot of marketing hype (and there is none better at the game than Apple) for something that isn't really filling a need. Some folks even think it's stupid.
Regardless, Apple fanboys who also happen to be chess fanatics (yes, I know there's a few out there) can rejoice. For there are at least 3 chess apps for the iPad now available on the iTunes store. These are Chess Pro, Chess-wise and tChess Pro.
Where is Chessbase in all of this? Or maybe they're just too busy thinking about the next stupid April Fool's joke that only their German sense of humour can understand.
