yup, and thats why i bother to ask questions i already know the answer too. one, because there is always the off chance i'll be proved wrong, and two, someone else might find it informative.
the whole "wishlist" seems very half baked. on the device, in the app store app, you have the option "Gift This App" which would go hand in hand with a wishlist. but as we know, there is no way to access your wish list, and certainly not someone else's. which is really where it's at. who's just going to randomly buy and app for someone? and even if you do/would you can only hope itunes would be smart/kind enough to tell you whether or not your "friend" already has it. see, if you're going to bother to have a "gift this app" option, (believing in the generosity of people) it only make sense that there be a way to see what your "friends" would want in the first place.
but for me, i don't really believe in wishing, and i certainly don't expect someone to "gift" me and app! so really my "wishlist" is just more of a "save for later" list, or bookmark, favorite, star.... something! it really is ridiculous how weak the app store app is. i mean on the computer you have all this great functionality, which is great, but the whole point to the iPad is it's portability!!! so i prefer to look for apps, portably.
now, being "stubborn" if you will, i'm used to having to find ways of doing things that are already "solved" by doing them other ways. so whats my solution to a "wishlist" on the go? email of course! taking advantage of the "tell a friend" option i email myself the app info. taking it a step further, i set up a filter/rule to put the ipad app emails in their own folder. and then i can just go to my email and voila, a wishlist! and then, when you are on the computer, you can go through and add them to the itunes wish list too.
