I do know that users are installing from the alternative CD in order to
work around graphics problems with the live cd. For instance, nouveau
locks up on their hardware, but they can do the alternate CD and
manually install nvidia. Searching for "Live" against
xserver-xorg-video-nouveau shows a couple dozen bugs in this class filed
over the past several releases. #1040495 and #1037915 are examples.
There's probably a bunch filed against the kernel and other X components
too. So, it's definitely a legitimate issue. But it's less common than
Doug suggests.
However, while the alternative CD is one way to work around these kinds
of issues it's not the only way. For instance, in those bugs the users
used "nomodeset" to work around it. Obviously, few users will know to
try that, but even so I don't think this is very strong justification
for keeping the alternative CD. Time would be better spent a) making
the kernel parameter workarounds more obvious to users, and especially
b) solving the actual bugs.
One complication we should consider is that when a user *can't* boot the
CD on their system for whatever reason, filing a bug report about it
becomes *very* hard. Since they can't boot, they can't invoke
ubuntu-bug to file a bug with auto-collected log files. They can't
manually collect log files either. They probably have no idea what
package to file the bug against, and maybe don't even know where to go
to file it (challenge: try getting to the +filebug page from
ubuntu.com). Chances are high that a lot of these problems are just not
getting reported, at least not through the channels we expect.
