My Dell Latitude D830 came with Microsoft Vista which, for the most part, has seemed like a prettied up XP without a lot of added useful functionality nor a substantial increase in stability. At the time I upgraded, I wrote that I was like so close to buying a Macbook Pro . I am sorry to say that I regret that decision even more today. What got me to that stage? Well, it's a long painful path and to be honest, I'm not at the stage (yet) that I'm ready to just give in and replace my fairly new laptop.
