I have some dumb newbie iPad questions: - do I have to re-purchase the apps that I have from my iPhone? I've found through itunes and syncing the apps that some of them are listed as "iPad" apps but the rest are not, and I know apps like GoodReader have an iPad version (right?). For some of them do you have to buy the ipad version separate? - will the normal iphone apps run on the ipad? Do they look awful or not run well, etc.? ... I know I had more but that is all I can seem to come up with at the moment. TIA!
