A prefix for the rich (who can often buy new games) or for those who travel (not boring, and it charges easily and quickly). Different pros: Cool graphics (I have not tried very heavy games), they have bells and whistles (films, covers), like a mini computer for entertainment. Got cons: Terribly easily soiled (the film fell off, the screen is dirty after 5 minutes). A rag will not help. And the disks are very expensive.
