Finally Linux 64-bit on my laptop - thanks to Ubuntu

I have been dreaming of using Linux day to day on my HP laptop which is installed with Windows Vista. I really Vista for its useless UI improvement (I don't really see any advantage that I can take on a daily basis) and the frequency it crashes or stop responding mysteriously. I have been trying Ubuntu and other Linux flavors for a while but only successful at the virtual machine level because they always have issue with my laptop hardware. When Ubuntu release its 9.1 release, I tried it out and it seems working perfectly (except hibernate/suspend) on the laptop. More importantly, this is the 64-bit version I am talking about. I am very happy because my laptop cpu has been underused because Vista I have is 32 but. Now I am able to unlock its potentially by running 64-but Linux on it. I am doing a lot of programming in several languages ranging from very low level as C to very high level as Haskell and Groovy. The performance is impressive, and clearly much better than when it runs Vista.

I now use half of the HD to run Ubuntu and rarely boot into Vista. Hopefully I will be able to completely switch off from Windows some time soon.
