Favorite out-of-the-box accessible Linux laptops?

[Linux for blind general discussion]

I am looking for a Linux machine to use in graduate CS courses. I probably
want Ubuntu or another common distro that comes with the screen reader (I
assume Orca) and other a11y stuff already installed. I like small, light
laptops (since I don't use the screen) that have decent memory and battery
life. Which machines are your favorites.

Thanks for the tip on VmWare the other day, BTW.
