i would prefer:
CREATIVE for - song format supported for the mp3 , sound quality,
more functions then ipod , long lasting battery, style, cool
looking design,screen colour is sharp . Convenient location if want
to send mp3 to repair.
IPOD for - Poseur value , cool looking design, material of the ipod
mini, lasting, laser engraving on the player
Samsung for - compact size, small looking.
weakeness in this brand :
Creative- Headjack problem ( not really sure if the new players
still have this problem , but my zen micro have this problem ) ,
Material of the mp3( plastic for those cheap ones
IPOD- transferring music to the player via itunes, it takes long
and quite troublesome if there is reapeated songs. Far location of
service centre, battery is in the player , cant change and remove
unless u send to service centre to change. Scratch complain that
have happen in IPOD nano and IPOD video casing.
Samsung - ?? too small , lost easily if not kept properly.
