i have to say i'm pretty satisfied with the specs & features of the iphone as announced in the keynote, so other things i want are more "wishlist" items. at the top of that list is push .mac email. second place would be an ebook reader (so i could finally ditch my palm pda).
other than that, the iphone is pretty much the ultimate cell phone that will meet every one of my geeky needs: excellent phone capabilities, calendar & address functions with sync capability, excellent web browser that can use wifi or edge, wide-screen video viewing, ipod functionality, to name a few (my only concern is the usability of the onscreen full keyboard for text messaging and email creation, but i'm counting on adapting to a point where lack of tactile feedback is not an issue). perfect!
