Similar to XP, for many users it would really help to see which users are 'available' and then to just click and enter the password. Although it is perhaps a little less safe, it would greatly enhance usability for the users. Also, it would be easier for XP users to get used to the Ubuntu look.
Think about it this way: There are two (2) keys required to open an account on the computer; the user ID and the password. By putting a list of user IDs on the screen a potential cracker only needs find the second key to go with any one of those IDs. Relatively, a much less arduous task.
This is widely recognised issue. So much so that corporate security policies very often require that the registry on Microsoft Windows systems be changed to stop them displaying the ID of the previously logged on user. This is in addition to changing the administrator account ID.
Surely, if one doesn't know how to do something, one owes it to oneself to learn how. Either that or settle for not knowing and accept the consequences.

I don't know of any XP systems that have a list of "which users are 'available'".
This is not a security risk. Relying on obscure user names for security is stupid. Instead use your real name and append the obscure one you wanted to use at the end of the password. Longer password=more security for real. On the other hand, i see no good reason for changing this default.
