It was only inevitable that Google would eventually offer a mobile ready version of its adsense platform. It’s been doing it to some degree with the parking companies for some time, although maybe not directly.
As one of the named investors in dotmobi this move is actually a bit late when you consider that there are already a number of other companies who were “first to market” and probably have gained an advantage with the mobile developer community.
In terms of the interface there’s no big change. It’s pretty much the same as any other adsense product with a choice of palettes etc.,
If anyone has a chance to play with it I’d love to hear how they get on
