Just to let you guys know, I've been listening to FLAC (compressionhow loaded is the cpu with a -2 FLAC file? also, how does the
level 2 or lower) tunes on my 3rd generation ipod running ipodlinux
(modified uCLinux) for the past few days. No skips or slow-downs
whatsoever using MPD to play music.
battery life compare against regular ipod use? not sure how
much would be due to FLAC vs. MP3/AAC and how much due to
ipodlinux vs. native ipod OS.
Not sure about CPU load, but I suspect not a whole lot. I have -8 playing comfortably (slows down a little during UI (what little UI I have) interaction if it's reading from disk at the same time). I haven't been able to get plain-old telnet to it working the past week or so, but I can telnet into MPD. I optimized a few functions a little in libFLAC and MPD in C and it was enough for now. I'll post those to the -dev mailing list in a bit, but I haven't been able to get very far with ARM asm (though reading it has given me great insight on how to optimize my C).
Battery life: >= 2 hours, that's the longest I've left it unplugged and
playing. No idea compared to the Apple software, I've only used the
Apple software it for a few minutes to make sure the hardware was
working right when I got it. I'll run a test this weekend and see how
long it takes to drain.
I guess my battery is dying. I only seem to get 2 hours +/- 15 minutes. I only get that much in disk mode or idle, too. I've never had power management on my ipod, so it was probably plugged in and at full charge for too long.

As such you will find that your batteries are probably wearing out faster due to increased usage (faster discharging and charging)
+ the lackof power management is an issue as well, as flac is less CPU intensive potential power savings could be had as soon as they get it working (fully)
