I believe there are 2 options...
1.) 24X CD Burner/DVD Combo Drive [included in Price]
2.) 8x CD/DVD burner (DVD+/-RW) with double-layer DVD+R write capability [add $89 or $3/month2]
If you have a desktop with a dvd burner then I would just go with the first option, if you don't currently own a dvd burner, and would like one, then I would go fot the second option. Be aware, however, that you can buy an internal dvd burner for your desktop PC for around $45 dollars, the one above is $90 dollars, essentially. Depends if you need to burn dvd's on the "go" or if this will be your primary computer.
