Here is some news from Tomdryer.com:

It looks like Ubuntu will be sold on three Dell systems starting on the 24th of May.

We will be launching a Linux based OS (Ubuntu) on the E520, 1505 and XPS 410 starting next Thursday, 5/24. We expect these systems to be less than 1% of our OS mix for the entire year which is ~20,000 systems annually. Please cover the huddle deck below with your team by EOB Sunday. If any questions come up, please let me know so I can address them before launch.

The goal of launching Linux is to continue to give our customers more choices to customize their new Dell. Providing more options to our Linux Enthusiast customer group will hopefully create even more Raving Fans!!

I agree that offering Linux to enthusiasts could create more Dell fans, but it is a shame that this is US-only. You can read more at DesktopLinux.com.
