Ubuntu Workstation - Dell inspiron 530

After a bit of consideration I have decided to change my computer setup a bit and go for a desktop and a laptop for mobility.
At the moment there is a macbook pro together with a 24” dell monitor.
The dell 24” will stay but I will get an inspiron 530 with a 22” screen.
A dual screen setup with a 22” and 24” screen, The workstation will be running Ubuntu linux(Hardy Heron version). The dell inspiron is sold in America with Ubuntu Pre-installed on it so this seemed the closest I could get to an out of the box ubuntu system. Hopefully there are not too many problems with installing Ubuntu.
Posting from an ubuntu machine soon! (I hope)
