I bought the device as my first MP3 player, plus the ability to copy photos off my camera while on holiday.
I loaded on 1300 tracks and backed up all my photos and data from my PC and it not takes a while to boot up, turning off the database helps the boot time if your tracks are organised into folders anyway.
I find the sound just fine, and the ability to record from LPs by plugging the device in to the stereo downstairs and then carry them back upstairs to split if required, if the LPs are in very good condition the H320 will automatically split the tracks, but it sometimes misses the gaps when recording from LP's as they never really go quiet.
One use I had not considered before I bought it was the voice recording option. The Mic is very good and seems to work very well, when placed in the middle of a table at meetings. Great for proving who said what and the auto level works well, everyone coming over loud and clear.
If you want a device just to play Mp3's this may not be the one for you, or if you judge a device, by its packaging, if you want a device which does several jobs well, then consider the H320 or its bigger brother the H340.
A couple of words of warning, the US version's of these devices do not have the USB to Go, so can not be used to copy direct from cameras, key-drives etc, so make sure you are looking at a UK spec system when price comparing. Also check your Camera is compatible via the iRiver site, if you want to use that feature.
