i think it will be a digital camera...or at least it should be. what could be more "fun" and "new" than that? besides, there needs to be a digital camera out there that is as easy to use as an ipod, with scroll/clickwheel access to everything. digital cameras from HP, sony, etc. have WAY too many buttons and are obnoxious. apple has enough experience with iphoto and isight to deliver a kick-ass hardware/software combo that's as elegantly simple as the ipod.
