The price is $130 because its the difference between the Arcade and the 250GB plus the 25-30% retailer markup on accessories. Thats my best stab at why they chose that particular price.
Now the question of worth is there I guess. If anyone is anal about game saves then having an internal external backup would be valuable. If you can store your saves on the HDD and the flash then you'll always have a backup. If the console bricks you have the external HDD and if the external HDD bricks you have the flash.
Tease.
