iTunes's money making scheme

I have an extensive library of music in my itunes account. I purchase items through the itunes store. I sometimes get huge collections, music videos, audiobooks, and movies (waiting anxiously for Dark Knight). What struck me as a little odd was the option to purchase ringtones out of some of songs people may already have. This may not concern a few of you, but for those of you with a Mac and an iphone may want to know the following.
As you know, the iphone can hold and play music. What it cannot do is play that music as a ringtone unless it was purchased. The process allows you to customize the ringtone. Say, 12 seconds of the middle of a pop song. After you choose the timing, you click purchase.
People who actually do this aren't using their Apple products to their full potential. Macs and iphones are not gimmicks, they are tools.
Instead of using itunes store to purchase ringtone versions of songs you already have, you can use Garage Band.
Simply import the song, edit it to your liking, then export as a ringtone to your itunes library.
That's just for a song you may want as a ringtone! The application can be limitless.
My ringtone is the grandious song you typically hear before a movie begins.
Hope this helps to deal with some of the limited ringtones choices that come with the iphone, and keep costs down on un-needed purchases on things you could do by yourself.
