I purchased a Sony PSP over the other gaming systems formost because of the Sony name.  My children have loved these gaming systems.  I find the games to be inexpensive when compared to the television gaming systems.  These handheld systems kept two very active boys occuppied on a long roade trip to the beach this past summer.  Accessories like a car charger was very expensive and well worth the money.  The system have been dropped too many times to count yet still work so that will attest to their durability.  Unfortunately, it did not survive being chewed upon by our Police K-9 when left...
