For many people the time to boot up their system is quite essential. Every second counts. Especially when it comes to comparisons of operation systems, 5 seconds less waiting seems to proof that one system is better that another… Well Mark Shuttleworth announced for Karmic further improvement on the boot time, and it looks like the Ubuntu developers did a good job.
On YouTube there’s a video which shows two (nearly) identical laptops. One runs Ubuntu Ubuntu Karmic Koala Alpha 2 and the other one uses Windows 7 RC. The windows system uses a Intel Core2 Duo Mobile T7250 which runs at 2Ghz where as the Ubuntu system only has a T7100 with 1.8Ghz.
