Andrew sent over a link to iPieces and describes it as follows- "Here's an interesting approach...Jumbo Games have a new range of iPad games out called iPieces. They combine an app with physical accessories. The games themselves are free from the App Store, but the accessories to play the games are £9.99."
He then asks a question which really made me think- "This begs the question as to whether these games will get banned when Apple realises it's not getting its 30% of the accessories' cost?"
