Samsung P3 Firmware best working update?

I don't own a P3.  Have you already purchased one?  If so, what kind of headaches are you experiencing with it?

What would you say are the strong points to the player and what are the weak points.  Been thinking about buying one for a while now and just have not pulled the trigger.

I have had the player for more than a year and it crashed once, can't even remember how long ago. In the past I used the 2.18 version, currently I'm using the 2.20 version for half a year at least.Main reason I haven't upgraded to 22 is laziness. 

Take note, I'm pretty much not using the video functionality, so I can't attest to the stability or lack thereof in the different firmware versions. It seemed to work fine with the 3-4 files I have tried. 

Only other buggy behaviour I have noticed is that sometimes the artist name isn't being updated when the song changes,

haven't bothered to triangulate a more specific set of conditions, mostly because I don't care, I'm not looking at the player much.
