I thought about just using .wav for simplicity but I wanted ID tags to show up on my Squyeezebox so I could browse the music library. WAVs don't natively support tags and there are work arounds but they can be messy and are not universally supported.

I'm very happy with FLAC and I keep a sister library of MP3s for the Zune but any music played out loud in the house comes from the flac libray.

With great power comes Awesome irresponsibility.
