Two copies of Tetris and Achtung Baby

I just bought a Motorola Droid and was faced with a problem I always forget about when I get a new phone.  If I want Tetris on the phone, I need to purchase it all over again.  This makes me think back to the Actung Baby album by U2.

I’m fine with copyrights, even if the life span of copyrights has gotten ridiculous.  However, it’s pretty ridiculous that I’ve actually shelled out for a copy of Actung Baby on cassette and again on CD.  It’s the SAME music by the SAME band that I’ve ALREADY paid for.  :/
