C'mon, let get serious. Why pro people with pro iPads using pro app have to cope from all those "oh, but my iPhone 4 doesn't have enough to room". This is like setting your Ferrari max speed to 20 miles/hour because all those folks with bikes can't follow. You can have a simplified version of ASP for them (like before), or they can use full screen mode. BTW. You can use different prices for them.
