Reward hardware manufacturers that create drivers for linux by promoting their products, this might encourage them to do so more often.

Kde's FolderView allows you to have files from different folders shown in your desktop, even allowing filtering. It seems rather usefull. Gnome should have something similar.

(I know it is a gnome suggestion, but I think it's good to post it here)

When you rearrange files in a folder Image Viewer still follows the arrangement by name order. Please make it follow whatever arrangement the folder has.

Option for having different applets on different workspaces in gnome-panel.

A big complain from people that are considering switching to linux is that they believe playing movies (codecs), dvds, etc is hard in linux, when all you need to do is install a few simple packages. Since most of these packages cannot be included by default, it would be nice if the firefox home page that first appears on a fresh install had a link to a guide with suggested packages to install, with a warning that some of these packages are not open source and might not be free (as in beer) in some places, and possibly from 3rd parties.

My list would include ubuntu-restricted, build-essentials, and possibly some of the packages in medibuntu which include software former M$ users would recognize like adobe, skype, google-earth, etc. I'm sure there are plenty of other packages that could be suggested in the comments.

It would also be nice if this page would explain how programs are installed in ubuntu and the advantages of using software from the repositories.
