Is there an updated list of current laptops which have been found to work well under Ubuntu (other than the common "n best linux laptops of YYYY" articles)? There appears to be a page for Ubuntu-certified hardware but laptops are not among the categories of hardware listed.

At the page you linked, look under "Ubuntu Desktop certified hardware" There is a list of desktops and laptops.
I am thinking this list is an up to date compilation of the latest Ubuntu compatible laptops and desktops.
