There is a preliminary FOSS decoder for ALE out:

You could have SlimServer transcode ALE --> FLAC
without loss of quality.

That said, I'd much rather people didn't use closed
formats.

Agreed!

I don't see much reason to ever use ALE, though it's certainly nice to
now have the ability to decode it if necessary. Lossless formats are
still too bulky for portable players, so even though an iPod supports
it, it doesn't seem very practical.

That leaves AAC and MP3, since the iPod supports them but not Ogg
Vorbis. Since AAC seems to give better quality than MP3 for the same
data rate, then it makes the most sense to keep your primary archive in
FLAC and convert to AAC for the iPod as necessary. Both AAC and MP3 are
patent encumbered, so you're forced to choose between two evils.

But if you're lucky enough to have some other portable player that
supports Ogg Vorbis, then you can produce Ogg Vorbis versions from your
FLAC masters and not deal with proprietary formats at all. That's the
route I've chosen by buying an iRiver 340.
