I switched from an MBP to a Dell Precision 5520 with Ubuntu, then upgraded to a 5540 and am looking forward to the 5760. My colleagues are also using the 5540. These machines have been rgreat for us. We don't have much time to spend to tweak things, instead do a clean reinstall every few weeks and apply all upgrades as quickly as they come. Dell and Canonical have been supporting these machines quite well, in our experience.
