From my experience, If you install both the operating systems on identical hardware, Ubuntu’s performance is significantly higher than that of Windows 7.
In fact, if you were to pull out a 7 year old computer from a junkyard, Ubuntu will work flawlessly.
Ubuntu is bundled with Movie Player, and also requires downloading codecs.
With Linux, there is rarely any need to download the drivers manually.
Linux also has the ability to download proprietary drivers (The ones from Nvidia and ATI), unlike windows where we have to manually download and install a driver for everything.
3) Media - Windows comes with Windows media player, which is pretty much useless without codecs, as majority of the videos/movies that we watch require codecs like Xvid.
So there is a need to download a codec pack before Windows media player becomes fully functional.
The question I ask is “What good is an operating system, if it doesn’t provide the basic features?
