I often hear that Ubuntu is not visible on Dell's website.

After reading your comment, on a lark I typed www.dell.com/ubuntu . voila! that URL does take you to a Ubuntu specific page :)

Do you think that people browsing Dell site are going to type in the ubuntu url? They may never heard of it.

On the other hand, Dell is capable to upsell vista with xp. Why are they not capable to offer ubuntu using the same mechanism?
