The only potential issue would be the Graphics card. That particular card uses Optimus which has been known to cause issues with Ubuntu and other Linux distributions. If the bios allows you to turn off Optimus and specify either Nvidia or Intel as the graphics card there should not be an issue.
There are some questions her about your video card:
The other items that can cause issues are:
- Web Camera
- Sound Card
- Backlit Keyboard
- Special Function Keys
Does your system have any of those items?
If you already own the system or have access to one you could try booting to an Ubuntu live CD to see how things work.
It would appear that there are some potential issues - I found this thread: http://en.community.dell.com/techcenter/os-applications/f/4457/t/19530230.aspx
