A large number of "Windows Media Plays For Sure" devices will also support it, like the Xbox and Squeezebox. Not to mention native support in newer versions of Windows Media Player (which *ahem* is installed on something like 70% of all computers). Very broad support base overall, assuming you're using a Windows platform or have a mobile device that's designed for such. For Apple, as mentioned, ALAC is the better choice. flac will almost always require third-party software (for example, it's supported on Windows Mobile, with a separate decoder (similar to how there's a Vorbis plug-in for WMP)). For at-home use it really doesn't matter what you pick, as they're all lossless - my inclination is towards WMA-L because basically any modern Windows PC will read it out of the box, but flac, ALAC, or even raw wav, are all fine as long as you have the space and appropriate software package.
For portable players is where it gets more complicated - if you have a player that supports a given lossless format, that's basically what you use (if you absolutely just have to have lossless), otherwise stick to WMA or mp3 and be finished with it.Edited by obobskivich - 3/6/13 at 5:51am
