Aha!

I just figured out why we all have to start saving up instantly to buy the next version of the iPhone the moment it becomes available - the one thing they left out of that most excellent device is a voice memo feature. Or at least if it's there I haven't figured out where yet. Because what would make more sense? And you can save an awful lot of stuff (or a lot of awful stuff) in 8 gigs. Voice memos would be cool. 

Since it is possible to change the voicemail message easily one could record a note there, but being answered by a grocery list might tend to confuse the hopelessly unnerdy. (And no, it's not possible to call yourself. I just tried. All you get is a bunch of serious beeping, which is no help at all.)
