Vector Tanks Extreme is awesome on the iPhone. So a worthy pickup for sure for the iPad. the non-Extreme version is also excellent while being different enough in style to warrant a separate purchase. I don't have an iPad, yet, but knowing that these (at least Extreme) are getting a free iPad HD update makes an eventual purchase all the more inevitable. Once Carcassonne and Reiner Knizia's Samurai get their promised iPad updates, it's going to be near impossible to resist....
