Sounds like a lot of money for something iTunes can do for you for free (burn and re-import as mp3 or whatever). Esp. considering that there's some loss of quality on the re-encode.
There are some free tools (albeit technically illegal in certain countries) that will strip the DRM without any loss of audio quality (or loss of meta-data). Since Zune supports the AAC codec, I'd personally go this route if I were to switch to Zune. (But since
even the Zune tattoo guy has jumped ship to iPod, it doesn't seem like the way for me to go- sorry I couldn't resist

).
Also, if you stick to buying iTunes Plus tracks, this isn't an issue. And I think to Apple's credit they've pointed out the DRM on their regular tracks since the debut of iTunes Plus ... and the only reason they're not 100% DRM-free on music is because certain music labels refuse to let them (afraid of ceding even more control to Apple) even though those same labels allow Amazon and other stores to sell the same music DRM-free.
