Footnotes:

Yes, except after removing from PC or total battery failure.
The iRiver firmware will read playlists larger than 999 songs, but will only actually load the first 999 into memory.
Only 1 song in queue.
No recording.
If database scan is on, and some disk fragmentation, a full H140 (6997 tracks on mine with 4MB free) will take up to around a minute to load. Without DB scan, 20 seconds is normal.
Functionality limited. Stock iriver firmware can only delete music files while no song is currently playing.
Limited to 100 tracks (added with the 1.31 firmware).
The supported 'Gap delete' is something totally different from gapless playback. Gapless playback means to add no pause between the tracks, so that e.g. for a DJ mix split into multiple tracks, the track change is unnoticeable during playback. Gap delete just means cutting silence from the beginning and/or end of the track itself.
Not low bitrates - less than 96kbps doesn't appear to work.
The 1.31 firmware has a minesweeper game.
Stock H3xx firmware is only capable of playing XviD video at 10 fps.
iPod has soundcheck, which is similar in purpose to Replaygain.
The iPod 5G (aka "iPod Video") is capable of playing MPEG-4 and H.264 format video using dedicated decoding hardware. Other iPod models can not play video.
The iPod can do bookmarks for Audible files and audiobooks, but not for other files.
There are some games available for purchase.
Currently support MPEG-1 and MPEG-2 video streams, see PluginMpegplayer.
Cowon firmware equalizer is simplified and not fully parametric (only gain is adjustable on an arbitrary non-dB scale).
iAudio X5/X5L only.
The stock Sansa firmware is capable of MSC and MTP mode. Sansa requires reboot when in MSC mode, and doesn't when using MTP.
X5 Notes:The X5 does support FLAC, but not with 48 kHz. And deleting files is possible, but not that easy (switching to USB host mode required).
Only on target platforms which actually have FM tuner hardware which is supported by Rockbox. See Buyers Guide note #1 for a list of working FM record targets.
The Rockbox WPS currently supports only cover art. Thus both .m4b chapter and PNG support is lacking. Possibly the Mpegplayer extra could be adapted to play/display .m4b Audiobook files.
