T7 :
I bought this neat device EAN=8808979896172 Ref=AH69-01705C a couple of years ago, and today December 2008 the device crashed my Laptop and went hotter than hell…
I fear the battery has some issue, so I put it in the freezer…
Of course the 1 year old warranty is over …
Hopefully 10 min I got it back and he resurrected … happy ending…
It seems also to happened on ipod (check link)
Anyway did you know about this Crimosoft treat:

#RockBox gave me some info of the internals :
< pamaury> the SoC is STMP3550 < pamaury> it's a super strange 24-bit DSP with general purpose instructions < pamaury> and it uses raw NAND Flash
