I ordered it from Dell earlier this week and it should be arriving before the end of next week. The main reason I ordered from Dell is that I wanted to pick and choose a high-end machine that would last me the next couple of years.

It has the standard Dell XPS options plus:

... As well as a 24" monitor for work and two power adapters (one for work one for home, makes travel easier). It will have the Windows partition shrunk from 200Gb to around 40Gb and will be dual-boot Ubuntu 8.04, with Ubuntu being the standard, Windows probably running through VirtualBox

I can't wait.
