On the drop-down box on each application's page (next to the "Buy" button) there's now an option that says "Gift This App." From that point, you then just enter in details like name, e-mail address and the message that you want to include.
Apple has long let people gift music albums to friends, but being able to gift applications is pretty cool. There are times I really want to recommend an app to my fiance -- and I know he'll forget about it -- but if I can gift it to him, we can bypass the amnesia. Hey, it's a nice surprise AND a nice app.
It's also a solid alternative to using iTunes Gift Cards if you just want to buy someone a certain application.
Please note, you can only give users in your country gifts -- so keep that in mind, especially if you have more than one iTunes account.
Let the app gifting begin!
