Not required, but definitely recommended (at least by me!)
No major bugs, but it's good to get eepe (the PC software) and er9x versions synced. Then you can upgrade the firmware as the spirit moves you, and you'll be staying in sync with the lastest versions.
And eepe is great... you can back up your models to your PC, edit models on your PC, etc. It's really nice.
(and by PC, I mean "and linux and mac"!)
