Linux is (starting up) so much faster, because the GUI doesn't influence the performance so much. Most Linux operating systems look quite well, without "demanding" graphics. Ubuntu for example needs at minimum only 128 MB of RAM!
Also, because there isn't that much malware developed for Linux, you don't need your virus scanner to be "scanning ahead" when you are working with your system. Scanning after downloading a file is enough (but that is more to make sure your Linux pc won't become a "stepping stone" for virusses trying to spread).

Gazz, I think I should tell you that you probably mean "bundle". "bunch" is used in case of flowers or so.
