My old laptop died. The bottom of the screen was black. It died some time ago when I was in New York. That was fortunate because laptops are much cheaper in the US. So I bought a cheap new laptop and was still under the legal limit of what I could import.
The system I bought, a compac presario CQ60 came with Vista. So I started using Vista. After working with it for a few weeks, I found that I had a steep learning curve behind me and came to the conclusion that it did not really work for me. So I decided to give Ubuntu a spin as well.
Now after two weeks of Ubuntu, I have learned that Ubuntu provides me with superior functionality. The version of Vista was "home edition"; when you compare this you find that in a comparison with Ubuntu, it is cripple ware. The things that make Vista professional useful are the same things that are to justify the much higher price.
Given that I do a lot of things on MediaWiki installations, having the same operating system makes it easier. My networking is more stable, the editing of scripts is superior. I think I am going to stick with Ubuntu.
