I am pretty sure the iCade was an April fools joke from think geek. I don't know if April 1st is the same in the rest of the world but in the states people play pranks on each other and on their web sites.
iPad has been out here for weeks and is interesting but the apps need to catch up. Plus, if you already have an iPhone, there is less of a value proposition than if you don't which is why I don't have one.
