Well, not always. Far from it. For at three years, Dell has given their customers the opportunity to buy Roxio CD Creator, or Nero in some cases, but Record Now by Sonic (which is owned by Roxio) has been the default CD burner software on Dell Dimensions, Inspirons, Latitudes, XPS and home or budget computers.
Sonic is the low end copying software, but it has had that one advantage of limiting the errors the user could make, by automatically finalizing the disc unless the user went out of their way to meddle with things.
Sonic bought Record Now in December, 2002. They were, in turn, purchased by Roxio, in August of 2005... but little change was made in the Sonic - Record Now - Software. Dell clearly has some interest in Roxio and or Record now, but I haven't bothered to look it up.
Clearly, Roxio is behind the fence on this one, because Nero is universally more popular. You can hardly give Roxio away. It sells in our Wal-Mart for $32... where Nero 7. Ultimate is $109, and Nero 7 Elements is $39... but available elsewhere for $3.00
The problems caused by users in opening, closing, copying, failing, etc., forced all computer resellers to handle a version of burner softrware that would produce copies that users could not damage.
